The inclusion of a query concerning the presence of snoring in a questionnaires used by the Allergy Service of Childrens Hospital Los Angeles (CHLA) uncovered a significant number of patients who were experiencing prolonged and discomforting symptoms owing to previously undiagnosed obstructive sleep apnea (OSA) caused by adenotonsillar hypertrophy. Of 352 patients who were discharged with a diagnosis of OSA and tonsillectomy and/or adenoidectomy at CHLA in 1996-1997, a retrospective study of the first 45 randomly selected patients who agreed to participate in a telephone interview was performed. Analysis revealed that all patients experienced severe and discomforting symptoms with all describing severe or moderate snoring. Other symptoms included chronic mouth breathing (84%), frequent otitis media (64%), sinusitis (56%), sore throat (51%), choking (47%), and daytime drowsiness (42%). Other symptoms included poor school performance, enuresis, poor appetite and/or weight gain, dysphagia, and vomiting. Symptoms began at a mean age of approximately 2 years ("birth"-9 years), and the mean period of time between the development of significant symptoms and OSA was 3.3 years (6 months-13 years). Delay between onset of significant symptoms and surgery was > 1 year in 82% of the patients, > 2 years in 51% of the patients, > 4 years in 31% of the patients, and > 6 years in 13% of the patients. Forty percent of patients were self-referred to an otolaryngologist for treatment despite their primary care physician being aware of the symptoms. These results indicate that patient with OSA experienced prolonged morbidity and delays in treatment, which is probably widespread. Physician, parent, and third-party factors were found to have contributed to the delays in treatment.

RhinoSleep was developed to diagnose obstructive sleep apnea (OSA). The RhinoSleep consists of a soft catheter, a measuring probe, and a computer. The soft catheter is inserted through the naris into the esophagus. The catheter is connected to the measuring probe, which creates and sends a continuous noise signal into the catheter. When the catheter is compressed during an obstruction, the sound reflections change, making it possible to identify both the level and the duration of the obstruction. Sixteen OSA patients were examined using RhinoSleep and daytime polysomnography simultaneously. With RhinoSleep, we successfully examined 13 cases. This trial study identified problems with RhinoSleep, such as vomiting of the catheter, hardware instability, and the criteria decision for the analysis of OSA.

Bariatric surgery leads to sustainable long-term weight loss and may be curative for such obesity-related comorbidities as diabetes and obstructive sleep apnea in severely obese patients. The Roux-en-Y gastric bypass has become the most common procedure for patients undergoing bariatric surgery. The procedure carries a mortality risk of up to 1 percent and a serious complication risk of up to 10 percent. Indications include body mass index of 40 kg per m2 or greater, or 35 kg per m2 or greater with serious obesity-related comorbidities (e.g., diabetes, obstructive sleep apnea, coronary artery disease, debilitating arthritis). Pulmonary emboli, anastomotic leaks, and respiratory failure account for 80 percent of all deaths 30 days after bariatric surgery; therefore, appropriate prophylaxis for venous thrombo-embolism (including, in most cases, low-molecular-weight heparin) and awareness of the symptoms of common complications are important. Some of the common short-term complications of bariatric surgery are wound infection, stomal stenosis, marginal ulceration, and constipation. Symptomatic cholelithiasis, dumping syndrome, persistent vomiting, and nutritional deficiencies may present as long-term complications.

Tonsillectomy may be performed as an outpatient procedure because post-tonsillectomy hemorrhages occur during the first few hours, and therefore are diagnosed before discharge, or occur after the sixth day. Nevertheless, not all patients are eligible for outpatient tonsillectomy. Both the ENT surgeon and the anesthesiologist must identify children who cannot be operated as outpatients because they do not satisfy the social criteria for discharge on the day of surgery (their parents do not speak French, they live too far from the hospital, etc.) or because they have individual risk factors for complications unrelated to their tonsils, such as bleeding disorders or related to their tonsils, such as a history of obstructive sleep apnea due to enlarged tonsils, particularly for young children. The anesthetic protocol must minimize the risk of postoperative nausea and vomiting. After tonsillectomy, the child may be discharged from the recovery room if he is fully awake, with no dyspnea and no oral bleeding, and is able to swallow liquids, without repeated vomiting.

Intermittent vagus nerve stimulation can reduce the frequency of seizures in patients with refractory epilepsy. Stimulation of vagus nerve afferent fibers can also cause vocal cord dysfunction, laryngeal spasm, cough, dyspnea, nausea, and vomiting. Vagus nerve stimulation causes an increase in respiratory rate, decrease in respiratory amplitude, decrease in tidal volume, and decrease in oxygen saturation during periods of device activation. It usually does not cause an arousal, or a change in heart rate or blood pressure. Most patients have an increase in their apnea-hypopnea index (AHI). Patients with VNS can have central apneas, obstructive hypopneas, and obstructive apneas. These respiratory events can be reduced with changes in the vagus nerve stimulator operational parameters or with the use of CPAP. In summary, there are complex relationships between epilepsy and obstructive sleep apneas. In particular, patients with refractory epilepsy need assessment for undiagnosed and untreated obstructive sleep apnea before implantation of vagus nerve stimulator devices. Patients with vagus nerve stimulators often have an increase in apneic events after implantation, and these patients need screening for sleep apnea both before and after implantation.

Roux-en-Y gastric bypass (RYGB) may represent a superior alternative to reoperative fundoplication in patients with symptomatic failure. Our goal was to assess early outcomes of patients after RYGB for failed fundoplication. Records of patients who underwent fundoplication takedown and RYGB from March 2007 to June 2013 were reviewed for demographics, comorbidities, operative findings, and perioperative outcomes. Data are reported as medians (range). Forty-five patients who had undergone 64 prior antireflux procedures (range, one to three fundoplications) were identified. Median patient age was 56 years (range, 25 to 72 years) with a body mass index of 33 kg/m(2) (range, 22 to 51 kg/m(2)). Most patients had comorbidities: hypertension (60%), anxiety/depression (44.4%), dyslipidemia (33.3%), asthma (31%), obstructive sleep apnea (26.7%), arthritis (22.2%), and diabetes (11.1%). Median symptom-free interval was 3 years (range, 0 to 25 years). All patients had an anatomic reason for failure: 83 per cent had a hiatal hernia and 35 per cent had a slipped Nissen fundoplication. The procedures were accomplished laparoscopically in 28, robotically in 13, and open in four cases. Median operative time was 367 minutes (range, 190 to 600 minutes) and estimated blood loss averaged 100 mL (range, 25 to 500 mL). Five patients (11%) required reoperation: one for an anastomotic leak, one for anastomotic obstruction, and three for early obstruction resulting from adhesions. Two patients developed respiratory failure requiring prolonged mechanical ventilation. Length of stay averaged four days (range, 1 to 33 days) with two readmissions: one for melena and one for vomiting and dehydration; neither required intervention. There was no mortality. At 11 months of follow-up (range, 2.3 to 54 months), 93.3 per cent of patients were symptom-free. When primary fundoplication for gastroesophageal reflux disease fails, fundoplication takedown and RYGB can be accomplished safely with minimally invasive techniques. The conversion to a RYGB has an acceptable perioperative morbidity and excellent early symptom control, and, therefore, should be considered for reoperative patients gastroesophageal reflux disease.

We report a successful awake insertion of the i-gel supraglottic airway device under dexmedetomidine (DEX) sedation in a patient with severe obstructive sleep apnea syndrome and symptomatic angina. A 71-year-old man was scheduled for open stoma closure under general anesthesia. Given the patient's history of difficult mask ventilation during anesthesia for resection of rectal cancer, we decided to perform awake i-gel insertion under DEX sedation and regional anesthesia with lidocaine. The i-gel was inserted successfully with no vital sign change or vomiting. We also performed transversus abdominis plane block and rectus sheath block with ropivacaine, as severe respiratory suppression due to continuous intravenous fentanyl infusion had been observed in the previous operation. No vital sign change or respiratory suppression was noted upon recovery from general anesthesia. Awake insertion of a supraglottic airway device, such as i-gel, under DEX sedation can be effective for airway management in patients with severe obstructive sleep apnea syndrome.

This brief communication regards the indications and complications for and rates of readmission following lingual tonsillectomy. The National Readmissions Database (NRD) 2013-2014 was queried for all cases of lingual tonsillectomy occurring from 2013 to 2014. Among 602 lingual tonsillectomies (mean age 36.5 years, 58.2% male), the common indications for surgery were obstructive sleep apnea (58.7%), lingual tonsil hypertrophy/infection (18.8%), and neoplasia (15.9%). Overall, 49 (8.2%) of the cases were readmitted (95% confidence interval, 4.8%-13.5%), with an average readmission duration of 3.0 days and average readmission cost of $25.4K. The most common diagnoses at readmission were bleeding (1.9% of all lingual tonsillectomy cases); dysphagia (1.7%); fever, nausea, vomiting, or diarrhea (1.6%); acute pain (1.6%); and airway obstruction (1.4%). There were no mortalities during primary or subsequent admissions. Lingual tonsillectomy across age groups is relatively free of adverse events, with overall readmission and complication rates similar to those of palatine tonsillectomy.

Although one of the most commonly performed surgical procedures in children and frequently performed as outpatient surgery, the postoperative course following tonsillectomy may include nausea, vomiting, poor oral intake, and pain. These problems may last days into the postoperative course. Although opioids may be used to treat the pain, comorbid conditions such as obstructive sleep apnea may mandate limiting the dose and the frequency of administration. Adjunctive agents may improve the overall postoperative course of patients and limit the need for opioid analgesics. Dexamethasone is a frequently administered intraoperatively as an adjunctive agent to decrease inflammation and pain, limit the potential for postoperative nausea and vomiting, and improve the overall postoperative course. The following manuscript reviews the use of dexamethasone to improve outcomes following tonsillectomy or adenotonsillectomy, discusses the controversies regarding its potential association with perioperative bleeding, and investigates options for dosing regimens which may maintain the beneficial physiologic effects while limiting the potential for bleeding.
