Introduction: The sudden sensorineural hearing loss is a devastating condition that could be a complication of some medical or surgical procedures. Objective: To report a case of sudden sensorineural hearing loss after general anesthesia to laparoscopic colecistectomy. Clinical findings: Male, 63 years, habitual smoker, with previous diagnostic of chronic obstructive pulmonary disease, who was submitted to laparoscopic colecistectomy under general anesthesia with sevoflurane. INTRODUCTIONHearing loss followed by non-otologic surgical procedures is not often mentioned in the literature, it is associated to cardiopulmonary bypass and rachidian anesthesia most of time.Perioperatory hearing alterations is a little reported process, though it seems to be more frequent from surgeon and anesthesiologist viewpoint.
Disruption of IHC stereocilia and loss of OHC in the basal turn of the cochlea following noise exposure (90 dBA noise for 8 hours) 6 months earlier. Disruption of OHC stereocilia following administration of the aminoglycoside antibiotic kanamycin. Sickle cell disease is a general term for a group of genetic disorders caused by sickle hemoglobin (Hgb S). Vasoocclusive crises are caused by sickled red blood cells that obstruct capillaries and restrict bloodflow to an organ, resulting in ischemia, pain, and organ damage. Because of its narrow vessels and function in clearing defective red blood cells, the spleen is frequently affected. Bone is also a common target of vasoocclusive damage, especially when the bone is particularly weight-bearing. A recognized type of sickle crisis is the acute chest crisis, a condition characterized by fever, chest pain, and pulmonary infiltrate on chest x-ray. Sickle cell disease (SCD) is one of the most common genetic disorders in the United States. An estimated 50% of patients in sickle cell crisis (ie, pain crisis) experience acute abdominal pain, which often is difficult to differentiate from acute cholecystitis.
Cholecystectomy (ie, removal of the gallbladder) is the standard surgical intervention for the diagnosis of cholelithiasis in patients without a chronic illness. Cholelithiasis typically is observed less frequently in healthy children who do not have a chronic illness.
Children with chronic hemolytic disorders generally have an increased risk of developing pigment gallstones.
Brown pigment stones are soft, crumbly aggregates that often form in the bile ducts of patients with a history of chronically infected bile above biliary strictures or cholesterol cysts. The current recommended treatment for children with SCD who are diagnosed with cholelithiasis is elective laparoscopic cholecystectomy. Risks associated with erythrocyte transfusion therapy among patients with SCD may include an increased risk of exposure to infectious agents and allosensitization to erythrocyte antigens.
The primary goal of elective cholecystectomy is to prevent complications associated with emergency surgical intervention. Knowledge of the specific developmental characteristics of school-age children is important for nurses and other pediatric surgical team members. School-age children may experience anxiety before an unfamiliar or familiar medical procedure because of their increased cognitive ability. In the preoperative holding area, the circulating nurse and anesthesia care provider complete all required preoperative assessments for a pediatric patient before transferring the patient to the OR. He or she then performs an assessment and documents the patient's physical condition, including vital signs, height, weight, and skin integrity. The nurse should review the rationale and importance of implementing postoperative strategies, such as deep breathing exercises with the child. The perioperative nurse offers the child the opportunity to select a scented oxygen mask (eg, cherry, grape, strawberry) for use during anesthesia induction in the OR. Perioperative team members transport the pediatric patient on a child-size stretcher to the OR suite and place the patient on a locked OR bed. The circulating nurse incorporates distraction techniques appropriate for the school-age patient (eg, discusses hobbies, school activities, clubs, team sports) to minimize the emotional distress often experienced by children of this age group.
Pediatric patients with SCD can experience bleeding diathesis and a sudden hemoglobin drop during the postoperative period even after an uneventful laparoscopic cholecystectomy procedure. Supportive perioperative interventions for the patient with SCD, therefore, include careful attention to ensuring adequate oxygenation, hydration, and acid-base balance.
The surgeon uses electrosurgery to make a 1-cm umbilical incision and dissect through the abdomen until the fascial tissue is entered. The surgeon places trocars and instruments into the 5-mm ports to grasp and elevate the gallbladder and then bluntly takes down any adhesions and grasps the infundibulum. The surgeon removes all surgical instruments from the patient's abdomen and deflates the patient's abdomen by allowing the carbon dioxide to escape via the ports, after which he or she removes the ports. The circulating nurse and anesthesia care provider transport the patient to the postanesthesia care unit (PACU) after the surgical procedure is completed. The major benefits of elective laparoscopic cholecystectomy include shorter hospitalization, decreased postoperative discomfort, a shorter interval before returning to normal activities, (43) and increased respiratory efforts. Sarah, a 10-year-old African-American female with a history of SCD, was admitted to the pediatric unit at St Louis Children's Hospital with a suspected diagnosis of acute cholecystitis. Sarah's pediatric nurse started an IV in Sarah's left anticubital fossa and began administering IV fluids (ie, 5% dextrose in 0.45% normal saline with 20 mEq potassium chloride) at 80 mL per hour in preparation for the scheduled surgical procedure. The elective laparoscopic cholecystectomy procedure proceeded uneventfully, and although the surgeon identified some adhesions from the omentum to the gallbladder, she detected no other abnormalities except for mild hepatomegaly.
Sarah was transferred via pediatric stretcher to the PACU, and after she recovered for 60 minutes, PACU nurses transferred Sarah to the pediatric surgical unit.
Elective laparoscopic cholecystectomy in children has been described as a safe and effective alternative to the traditional cholecystectomy surgical procedure because of a shortened hospital stay and improved postoperative recovery.
Current guidelines for children with SCD experiencing symptoms of cholelithiasis recommend elective laparoscopic cholecystectomy to prevent complications such as acute cholecystitis and the risk of emergency surgery for an unprepared patient. The article "Treatment of cholelithiasis in children with sickle cell disease," is the basis for this AORN Journal independent study.
A minimum score of 70% on the multiple-choice examination is necessary to earn 2.3 contact hours for this independent study. This program meets criteria for CNOR and CRNFA recertification, as well as other continuing education requirements.
AORN is accredited as a provider d continuing nursing education by the American Nurses Credentialing Center's Commission on Accreditation. Verna Hendricks-Ferguson, RN, DNSc, CS, is an associate professor at Jewish Hospital, College of Nursing and Allied Health, Edwardsville, Ill. The physiopatologic mechanisms involved are diverse and complex and this become difficult the prevention and treatment.
Some circunstances which involve surgical work can simulate those alterations or can be of no notice because of its subclinical nature if audiometry is not done. Depending upon dose, drug administration can cause either a temporary or permanent threshold shift. In many forms of the disease, the red blood cells change shape upon deoxygenation because of polymerization of the abnormal sickle hemoglobin. Other forms of sickle cell disease include sickle-hemglobin C disease, sickle beta-plus-thalassemia, and sickle beta-zero-thalassemia. Reticulocyte counts are elevated, reflecting new red blood cells replacing the rapidly destroyed older cells - red blood cell life span is markedly reduced in this disease. It is usually infarcted before the end of childhood in individuals suffering from sickle cell anemia. Such damage may result in avascular necrosis (especially of the femur) and bone deterioration.


Given that pneumonia and intra-pulmonary sickling can both produce these symptoms, the patient is treated for both conditions. In contrast, cholecystectomy has been considered a controversial surgical intervention for children with SCD because these children usually display asymptomatic cholelithiasis. These are composed of poorly soluble calcium salts, especially calcium bilirubin, and are dark in color.
Undertaking these risks may be reasonable because of the decreased risk of postoperative morbidity with elective laparoscopic cholecystectomy compared to the traditional cholecystectomy procedure. Potential complications after emergency cholecystectomy in this patient population are associated with general anesthesia and the inability to implement recommended preoperative interventions, such as erythrocyte transfusion therapy. Child psychologist Jean Piaget, PhD, characterized children ages seven to 11 as being in the concrete operations stage of cognitive development.
They may have many questions related to medical procedures that require health care providers to give age-appropriate explanations using correct scientific and medical terminology before all procedures. Both participate in preoperative teaching for the parents to inform them about what their child will experience. Encouraging the patient's participation in selecting a scented mask and providing concrete information related to the surgical process and postoperative strategies are examples of appropriate developmental strategies nurses can implement to aid in meeting the developmental needs of school-age patients (eg, gaining self-control, developing self-competence). The circulating nurse reassures the patient and provides simple explanations of the intraoperative equipment using concrete terms, such as explaining that the purpose of the OR bed strap is to ensure safety and prevent accidental falls rather than to tie the child down. The circulating nurse encourages the parents to accompany their child to the OR until after anesthesia induction to reduce the child's fears.
The circulating nurse assists the anesthesia care provider during induction of general anesthesia and intubation of the child. The circulating nurse initially positions the pediatric patient in the supine position on the OR bed and positions two video cameras at the head of the OR bed. The pediatric surgeon, with the assistance of the scrub person, drapes the patient's surgical site. In addition, patients with SCD receive IV hydration therapy at a rate of one and one-half times the calculated maintenance amounts for 12 hours before elective surgery. He or she then inserts the Veress insufflation needle into the abdomen and then places a 10-mm epigastric port. The surgeon uses electrosurgery to remove the peritoneum from the gallbladder and then clear and reverse the triangle of Calot. The surgeon closes the umbilical fascia with interrupted 2-0 braided absorbable polyglactin suture. Pediatric patients with SCD usually are discharged four to six days after elective laparoscopic cholecystectomy. After undergoing numerous diagnostic examinations, the physician confirmed diagnoses of acute cholecystitis, prolonged prothrombrin time, and multiple pigmented stones in the gallbladder.
The nurse also administered prophylactic antibiotic therapy (ie, 1 g IV cefoxitin sodium) every eight hours for three doses in preparation for the surgical procedure. The surgeon bluntly dissected all detected adhesions from the omentum on the duodenum into the gallbladder and dissected the gallbladder free. Sarah's pediatric surgical unit nurse completed an admission assessment and then monitored Sarah's vital signs every four hours until discharge.
On her second postoperative day, the nurse slowly advanced Sarah's diet beginning with clear liquids, increasing to a normal diet as tolerated. The behavioral objectives and examination for this program were prepared by Rebecca Holm, RN, MSN, CNOR, clinical editor, with consultation from Susan Bakewell, RN, MS, education program professional, Center for Perioperative Education.
Psychologist Erik Erikson characterized children ages six to 12 as being in the -- -- stage of psychosocial development.
Encouraging the patient's participation in selecting a scented mask is an example of an appropriate developmental strategy that nurses can implement to aid in meeting the developmental needs of a school-age child. Submersion of the incision is allowed immediately after surgery because the incision is closed with collodion. Nelson, RN, BS, CPNP, is the pediatric nurse practitioner and sickle cell patient coordinator at St Louis Children's Hospital.
I was already decribed with almost all anaesthesic techniques from local anaesthesia to general one, discussing in each of the cases a series of self or associated mechanisms (1).In the case of epidural anesthesia or lumbar puncture, hearing loss has been often reported (1-3). This process damages the red blood cell membrane, and can cause the cells to become stuck in blood vessels.
It is common in people from parts of the world where malaria is or was common, especially in West Africa or in descendents of those peoples.
Unlike sickle cell anemia, these other forms of sickle cell disease are compound heterozygous states in which the person has only one copy of the mutation that causes Hgb S and one copy of another abnormal hemoglobin gene.
Often, the white blood cell and platelet counts are elevated, and these cells may contribute to vaso-occlusion.
This autosplenectomy increases the risk of infection from encapsulated organisms; preventive antibiotics and vaccinations are recommended for those with such asplenia. Currently, most physicians advocate elective cholecystectomy for children with SCD who display asymptomatic cholelithiasis to prevent symptoms of acute cholecystitis and the risk of requiring emergency cholecystectomy that may place them at risk of complications. Age and chronic hemolysis are identified as the major factors that increase the risk of formation of black pigment type gallstones in children with SCD. The purpose of this therapy is to reduce the percentage of hemoglobin S and increase the hemoglobin concentration to greater than 10 g per dL. Explanation of these procedures can be enhanced by the use of simple anatomy and physiology diagrams and concrete terms explaining why and how equipment functions.
The circulating nurse confirms the child's identity and the scheduled laparoscopic cholecystectomy procedure with the child's parents.
The perioperative nurse then develops a care plan for the pediatric patient with SCD undergoing elective laparoscopic cholecystectomy (Table 1). The nurse either places the patient's IV line preoperatively in the pediatric unit or in the OR.
The nurse evacuates the patient's urinary bladder via the Crede's maneuver (ie, massaging the bladder by pressing down on the anterior, superior surface of the abdomen). Depending on the patient's age, a four-cannula technique generally is used for the laparoscopic cholecystectomy procedure. Hydration therapy is continued into the postoperative period until the patient displays adequate oral intake, which usually occurs by the third postoperative day. The Circulating nurse maintains the room temperature at 80[degrees] F to 85[degrees] F (27[degrees] C to 29[degrees] C) during the procedure, ensures the patient is positioned properly, and is careful to determine that IV stability devices and dressings have not caused circulatory stasis.
The surgeon then infiltrates all surgical wounds with bupivicaine and closes the skin with subcuticular stitches of monofilament absorbable poliglecaprone. After receiving report, the PACU nurse assesses the patient's vital signs, oxygen saturation level, level of consciousness, circulation, pain, IV site, fluid rate, and hydration status, as well as the status of the surgical site and dressing and all related monitoring equipment.
The pediatric surgical nurse provides in-depth discharge teaching to the parents about the child's recommended activity level and restrictions, pain management, and diet.
Hematology-oncology team members evaluated Sarah and initiated medical interventions, including pain management and vitamin K administration. She was unable to locate Sarah's dominant artery; however, small branches of this artery were identified. During the surgical procedure and the postoperative phase, the nurse managed Sarah's pain with a continuous IV infusion via a computerized patient-controlled anesthesia (PCA) pump of 1 mg per mL of morphine sulfate (MS) at a rate if 0.5 mg per hour. The nurse assisted Sarah out of bed on the second postoperative day and encouraged her to increase her activity as tolerated, offering assistance as needed. The elective laparoscopic cholecystectomy procedure, however, offers a planned surgical intervention, reducing the risk of complications associated with emergency cholecystectomy.


Each applicant who successfully completes this study will receive a certificate of completion. This recognition does not imply that AORN or the American Nurses Credentialing Center approves or endorses products mentioned in the activity. Therefore, we are not always aware that this might happen, and even more, if we have in mind that the specific presentation and the beginning of the defict can widely vary (4), and that does not have great audiometric studies about and we cannot have an accurate idea of their clinical or subclinical incidence. It is important to know that "sickle cell anemia" is the proper name of a specific type of "sickle cell disease", and that "sickle cell disease" is a non-specific term.
The frequency of pigment gallstones is higher in this population because of a sustained increase in heme catabolism among children with SCD.
Black pigment gallstones are small, hard, and spiculated (ie, sharp body with needle-like points) and are made of calcium bilirubinate, inorganic salts (eg, calcium phosphate), and calcium carbonate.
Psychoanalyst Erik Erikson characterized children ages six to 12 as being in the industry versus inferiority stage of psychosocial development.
According to developmental theory, school-age children are focused on gaining a sense of control and competence during various activities; therefore, health care providers should strive to keep children informed of what to expect before all medical procedures. The circulating nurse also verifies that all surgical informed consents are present and complete. During the initial steps of the procedure, the circulating nurse and anesthesia care provider rotate the patient and OR bed for improved visualization. The anesthesia care provider rotates the bed into reverse Trendelenburg's and left-dependent position to help the adjacent viscera fall away from the surgical area. He or she further divides the patient's peritoneum along the gallbladder to mobilize it before removing the cystic duct. The surgeon uses tincture of benzoin and self-adhesive wound approximating strips to close the 5-mm port sites and applies antibiotic ointment and a sterile adhesive bandage strip on the patient's umbilicus.
The nurse also places warming blankets on the patient to enhance comfort and preserve the patient's body temperature. He or she also discusses recommended follow-up management with the physician and the surgeon (Table 2). Sarah recovered from the acute painful episode and was scheduled for elective laparoscopic cholecystectomy. While mobilizing and transecting the cystic duct, the surgeon determined that one of the distally placed clips appeared not to have approximated appropriately; therefore, the surgeon placed an endoloop proximal to the clips on the cystic duct stump.
In the event that Sarah experienced MS-associated side effects, such as pruritus, the nurse had orders to administer 25 mg diphenhydramine hydrochloride IV or by mouth (PO) every six hours as needed. The nurse discontinued Sarah's PCA, IV fluids, and IV medications during the second day and managed Sarah's pain with PO oxycodone 5 mg or acetaminophen with codeine every four to six hours as needed. For school-age patients with SCD, these benefits minimize feelings of fear and anxiety associated with Surgery and hospitalization and foster a sense of self-control.
AORN is provider-approved by the California Board of Registered Nursing, Provider Number CEP 13019. From all studies, it is estimated that from 10% to 50% of the patients who had espinal anaesthesia can undertake hearing deficit measured in audiometric way in low frequencies, though only one fourth of them presented clinical manifestations (1).
Because the different forms of sickle cell disease are quite different, one must be sure to specify the exact form of the disease in question. Prophylactic cholecystectomy also is appropriate for asymptomatic individuals who have a chronic illness (eg, SCD, diabetes) and those who have an increased risk of developing symptomatic gallstones. During cholecystectomy, the triangle of Calot serves as a surgical landmark to identify important structures. Allowing time before procedures for patient questions and additional explanations is recommended. In addition, the nurse documents the patient's allergies, NPO status, presences of prostheses, loose teeth, rashes, bruises, and any other pertinent information that facilitates safe patient care.
After induction of anesthesia, the anesthesia care provider inserts an orogastric tube for decompression.
The patient and bed are rotated into the reverse Trendelenburg's and left-dependent positions to aid in allowing the adjacent abdominal viscera to fall away from the surgical area. The surgeon places two clips distal to the intended line of division and one on the cystic duct approximately 5 mm from its insertion into the common bile ducts. Laparoscopic cholecystectomy also carries a small risk of complications for all patients related to required surgical treatments, such as anesthesia, blood transfusion, hemorrhage, and insufflation of the peritoneal cavity with carbon dioxide.
If the pruritus was unresponsive to diphenhydramine, Sarah's nurse could administer 2 mg of IV nalbuphine every one to two hours as needed. In other cases of local anaesthesia as blocking of plexes (5) or odontological anaesthsia with the blocking of nerve (6) it was also reported hearing loss.
Individuals are most often well, but their lives are punctuated by periodic painful attacks. Health care providers also should educate school-age children about self-control strategies, such as helpful postoperative strategies (eg, deep breathing exercises, relaxation techniques, counting during dressing changes), before scheduled surgical procedures to prevent postoperative complications and minimize feelings of anxiety. After the child is intubated, a staff member escorts the parents to the parent surgical waiting room where they typically wait until their child's surgical procedure is complete. The surgeon performs lateral retraction of the junction of the infundibulum (ie, funnel-shaped passage or structure) of the gallbladder and cystic duct.
He or she transects the cystic duct and divides the cystic artery with electrosurgery before removing the gallbladder. Additionally, the nurse had orders to treat other side effects associated with MS therapy, such as nausea and vomiting, with 4 mg IV ondansetron every six hours or 6 mg IV metaclopramide hydrochloride every six hours as needed. He also instructed Sarah's parents to make Sarah's follow-up appointment in approximately four to six weeks.
The common hepatic duct, gallbladder, and common bile duct function as a storage site for bile and a conduit for bile flow from the liver to the duodenum. The percentage increases to 36% among school-age children and adolescents (ie, 10 to 20 years of age) and to 50% by age 22. The surgeon creates a small hole in the gallbladder to drain it with suction, which prevents bile leakage into the peritoneal cavity, before removing the gallbladder from the gallbladder bed.
Overall, this patient experienced an uneventful recovery period after the surgical procedure.
He or she pulls the gallbladder out through the umbilical port in an endoscopic specimen bag. The surgeon inspects the gallbladder and irrigates and aspirates the area until it is clear. It is known that 0.4% of the patients submitted to spinal anesthesia undertake some type of hearing perturbation (1).
MICHAEL (20) has described sensorineural hypoacusis followed by mielography, lumbar punction and spinal anesthesia. From 10 to 50% of the patients who had epidural anesthesia undertook mesurable hearing defict in low frequencies, therefore less than one fourth is clinically known (1-3,20).
Audiometry done soon after surgery.From the cases of sudden sensorineural hypoacusis followed by non-otological surgery under general anesthesia, most of them refers to patients submitted to cardiopulmonary bypass syrgery (1,7).
In the current report, we have presented hearing loss associated to general anesthesia to laparoscopic surgery. In the revised literature, we discussed about 40 documented cases of hearing loss followed by general anesthesia, only one of them in relation to laparoscopic surgery, and the second reported, the current one, in relation to general anesthesia and laparoscopic surgery and the first in which sevoflurane was the only anesthesia gas used.
