Abstract
PURPOSE To examine the changes in measures of sleep apnea severity and hypoxemia on the first post-operative night (PON1) following expansion pharyngoplasty as a means to assess the safety of same day discharge after surgery. MATERIALS AND METHODS Prospective cohort study of subjects with moderate-severe obstructive sleep apnea who underwent expansion pharyngoplasty at a single academic sleep surgical practice. A WatchPAT study was performed on the night immediately following surgery (PON1) and comparisons were made to baseline sleep testing. RESULTS Twenty subjects who had a mean age of 45.7 ± 10.8 years old and a mean body-mass index (BMI) of 31.4 ± 3.2 kg/m2 were enrolled. Patients had baseline severe OSA with mean apnea hypopnea index (AHI) 39.4 ± 19.5/h, O2 nadir 80.8 ± 6.1 % and time with oxygen saturation below 88 % (T88) 12.3 ± 13.2 min. Measures of sleep apnea and nocturnal hypoxemia were not significantly different on PON1. AHI was increased by >20 % in 11 (55.0 %) patients. One patient demonstrated a >10 % worsening in O2 nadir, and 8 patients (45.0 %) demonstrated a >20 % worsening in T88. BMI over 32 was associated with elevated odds of worsening in T88, and anesthesia involving ketamine was associated with lower odds of a 20 % worsening in AHI or T88. CONCLUSIONS On PON1 following expansion pharyngoplasty, AHI and nocturnal hypoxemia are stable overall but variable on an individual basis. The decision for admission should therefore be made on a case-by-case basis. Further research is need to elucidate definitive predictors of worsening measures on PON1.

Abstract
Uvulopalatopharyngoplasty is a generally safe and widely accepted surgical procedure for the treatment of obstructive sleep apnea. Unfortunately, uvulopalatopharyngoplasty does not always result in success, and patients who initially experienced improvement in the severity of their obstructive sleep apnea may relapse. Proper patient selection and performing uvulopalatopharyngoplasty in conjunction with other surgical procedures that are directed at other sites of upper airway collapsibility may yield favorable outcomes.

Abstract
El síndrome de apnea-hipopnea obstructiva del sueño (SAHOS) se caracteriza por la obstrucción parcial o el colapso total de la vía aérea superior, de manera intermitente y repetitiva, por lo que, en un principio, se vio el manejo quirúrgico como una alternativa curativa para esta patología. Sin embargo, en la actualidad se reconoce que la cirugía, aun sin lograr tasas de efectividad muy altas de manera consistente, sí mejora la tolerancia y adaptación a la terapia de presión positiva, la cual sigue siendo la primera línea de manejo.Así, el primer paso antes de pensar en cualquier procedimiento quirúrgico es un adecuado diagnóstico topográfico, de modo que siempre se debe realizar una nasofibrolaringoscopia para identificar el o los sitios de obstrucción. Además, se sabe que el 75% de los pacientes presentan obstrucciones en múltiples niveles y que, cuando el abordaje se hace multinivel, se logra corregir el SAHOS hasta en un 95%. Entre los procedimientos vigentes se encuentran cirugías de nariz, paladar blando, amígdalas, base de lengua, estimulación del nervio hipogloso y procedimientos del esqueleto facial, así como procedimientos coadyuvantes, entre los que están radiofrecuencia e implantes de paladar.

Abstract
PURPOSE 1) Evaluate the effectiveness of a postoperative disposition protocol for upper airway surgery in patients with sleep apnea. 2) Compare the cost-effectiveness of outpatient and overnight observational sleep apnea surgery versus surgical intensive care admission determined by preoperative screening criteria. MATERIALS AND METHODS A new preoperative protocol for sleep apnea surgery was instituted at the Durham Veterans Affairs Medical Center in 2008 to triage patients undergoing sleep apnea surgery to one of three postoperative dispositions: intensive care, routine ward bed, or discharge home. An Institutional Review Board approved retrospective chart review of patients undergoing sleep apnea surgery between May 2008 and January 2012 was performed. Postoperative complications and cost comparisons were assessed between each of the three postoperative disposition groups. RESULTS 115 patients underwent sleep apnea surgery between July 2008 and January 2012. 11 patients were excluded leaving 104 patients in the final analysis. Median follow-up was 1.25months. Overall complication rate was 12.5%. Eight complications occurred in the group triaged to intensive care, and 5 occurred in those triaged to lesser levels of postoperative care. All serious complications occurred during the immediate postoperative period. Based on only room charges, $125,275 was saved over the 3.6years of this study. CONCLUSION A post operative disposition protocol can be effectively used to triage patients to less than intensive postoperative care. In institutions like the Durham VA, where sleep apnea patients were routinely triaged to intensive care, postoperative resources will be more efficiently utilized.

Abstract
OBJECTIVE Characterize complications following uvulopalatopharyngoplasty (UPPP) for obstructive sleep apnea. STUDY DESIGN Retrospective chart review. SUBJECTS AND METHODS Charts of patients undergoing UPPP at an academic teaching hospital from 1999 to 2005 were reviewed. RESULTS 345 consecutive patients (248 inpatients; 97 outpatients) were studied. The most common post-operative complication in the entire study was oxyhemoglobin desaturation (12.8%). Three patients suffered major complications (airway obstruction, pulmonary edema, arrhythmia). Regarding complications limited to the post-anaesthetic care unit alone, only 8.2% of patients had oxyhemoglobin desaturation after discontinuation of oxygen supplementation. Inpatients requiring supplemental oxygen on the ward had significantly higher mean AHI (37.4 vs. 31.4; p=0.05) and BMI (32.3 kg/m(2) vs. 28.9 kg/m(2); p=0.004) than those who did not. Those inpatients who were obese (BMI > 30 kg/m(2)) with an AHI≥22 were associated with an increased risk of requiring oxygen on the ward (odds ratio = 3.48, 95% CI = 1.56 - 7.78). CONCLUSION The incidence of post-UPPP complications is much lower than the literature has historically suggested. Selected patients should be able to safely undergo outpatient UPPP. Patients with higher AHI, higher BMI, or multiple comorbidities are at higher risk for postoperative complications and are most appropriate for overnight monitoring.

Abstract
Sleep apnea patients pose a challenge for surgeons, anesthesiologists, and surgical facilities as there is increased risk for anesthetic and postoperative complications. Precautions before and after surgery minimize these risks. Screening for sleep apnea should be done for all surgical patients. Safe perioperative management requires judicious use of narcotics and sedating medications, reducing upper airway edema, prevention of aspiration and deep vein thrombosis, blood pressure control, use of positive airway pressure, and proper postoperative monitoring. Although the literature lacks specific recommendations, the guidelines presented in this article are based on more than 20 years of experience and supported by peer-reviewed medical literature.

Abstract
Safe perioperative management of patients with obstructive sleep apnea (OSA) requires special attention to preoperative and postoperative care. Patients with OSA are more likely to have comorbidities including hypertension, esophageal and laryngopharyngeal reflux disease, coronary artery disease, and obesity. Obesity may also contribute to deep vein thrombosis and pulmonary emboli. OSA increases the risk for anesthetic and postoperative complications. The recommendations for measures for preoperative and postoperative management of OSA presented in this article are based on a culmination of 20 years experience supported by the peer-reviewed medical literature.

Abstract
A transitory increase in blood pressure (BP) is observed following upper airway surgery for obstructive sleep apnea syndrome but the mechanisms implicated are not yet well understood. The objective of the present study was to evaluate changes in BP and heart rate (HR) and putative factors after uvulopalatopharyngoplasty and septoplasty in normotensive snorers. Patients (N = 10) were instrumented for 24-h ambulatory BP monitoring, nocturnal respiratory monitoring and urinary catecholamine level evaluation one day before surgery and on the day of surgery. The influence of postsurgery pain was prevented by analgesic therapy as confirmed using a visual analog scale of pain. Compared with preoperative values, there was a significant (P < 0.05) increase in nighttime but not daytime systolic BP (119 5 vs 107 3 mmHg), diastolic BP (72 4 vs 67 2 mmHg), HR (67 4 vs 57 2 bpm), respiratory disturbance index (RDI) characterized by apnea-hypopnea (30 10 vs 13 4 events/h of sleep) and norepinephrine levels (22.0 4.7 vs 11.0 1.3 g l-1 12 h-1) after surgery. A positive correlation was found between individual variations of BP and individual variations of RDI (r = 0.81, P < 0.01) but not between BP or RDI and catecholamines. The visual analog scale of pain showed similar stress levels on the day before and after surgery (6.0 0.8 vs 5.0 0.9 cm, respectively). These data strongly suggest that the cardiovascular changes observed in patients who underwent uvulopalatopharyngoplasty and septoplasty were due to the increased postoperative RDI.

Abstract
We conducted a retrospective review of 347 consecutive patients who underwent surgical treatment for obstructive sleep apnea syndrome. We analyzed perioperative data to identify the nature and rate of complications in an attempt to determine whether intensive care unit monitoring is needed after uvulopalatopharyngoplasty (UPPP) and associated procedures including septoplasty, tonsillectomy, turbinate reduction, geniohyoid advancement, and tracheostomy. In the 347 cases, 14 complications occurred (4%), including 5 involving the airway, 5 postoperative hemorrhages, and 4 complications classed as "other," including dehiscence of a tracheostomy flap, abdominal ileus, urine retention, and increased creatinine concentration. We found no difference between preoperative lowest oxygen saturation and oxygen-saturation readings in the postoperative period and no correlation between complication rate and apnea severity. An association was detected between multiple simultaneous procedures and the development of complications: 50% of the patients in whom complications developed had undergone nasal procedures along with UPPP, compared with only 15% of the patients without complications. Except for one patient, all complications that occurred on the surgical ward were treated without transfer to the intensive care unit. Although surgery on the upper airway must be performed with caution in patients with sleep apnea, our findings suggest that UPPP is a safe procedure and that postoperative monitoring in an intensive care setting is not necessary for most patients.

Abstract
To verify whether upper airway surgery in obstructive sleep apnoea syndrome affects differently respiration in NREM and REM sleep, 22 patients were studied by polysomnography before and three months after surgical treatment. On the average, treatment improved respiration during both sleep states, but no significant interaction was found between sleep state and effect of surgical treatment. According to the response to treatment, three groups of patients were identified: the first group (N = 6), with an improvement in apnoea-hypopnoea index (AHI), percentage of sleep time spent in apnoea and hypopnoea (time in AH) and mean oxyhaemoglobin saturation (SaO2) in both NREM and REM sleep; the second group (N = 5), with an improvement in AHI only in NREM sleep, associated with improvement in mean SaO2 in both sleep states; the third group (N = 11), without any improvement in AHI and time in AH, either associated (N = 5) or not (N = 6) with an improvement in mean SaO2 in both sleep states. An increase in the percentage of hypopnoeas out of the total AHI after treatment could partly account for the apparent discrepancy between AHI and mean SaO2 behaviour in the subjects of the second group, but not in the patients of the third group who improved their mean SaO2. Mixed apnoeas occurred before surgery in six subjects; they remained numerous after surgery only in two subjects who did not show any SaO2 improvement. In conclusion, the degree of improvement in respiration after upper airway surgery was similar in every patient in NREM and REM sleep.

Abstract
A study was conducted to assess oxygenation and respiratory changes on the first and second postoperative nights after uvulopalatopharyngoplasty (UPPP) for obstructive sleep apnea (OSA). Twelve patients were postoperatively evaluated with 8-hour nocturnal polysomnography on four occasions: (1) PREOP--night before UPPP, (2) POPN1--first postoperative night, (3) POPN2--second postoperative night, and (4) 3MOS--3-month follow-up study. Results demonstrate that apnea index (AI) and respiratory disturbance index (RDI) were significantly improved at 3MOS from PREOP levels: AI (p less than 0.01) and RDI (p less than 0.05). There were no statistical differences from PREOP to POPN1 or POPN2 for AI, RDI, lowest oxyhemoglobin saturation (LSAT), or number of desaturations (#DESAT). One of twelve patients dropped LSAT greater than 10% from PREOP to POPN1 or POPN2 (82% PREOP to 71% POPN2). Patients were grouped by PREOP LSAT greater than or equal to 80% or less than 80%, and the postoperative change in LSAT was evaluated by comparing PREOP to a value averaging POPN1 and POPN2. Patients with LSAT greater than or equal to 80% decreased by 2.6%; patients with LSAT less than 80% improved by 6.2%. This change in LSAT between groups was statistically different (p = 0.02). These data suggest that in the majority of patients, preoperative indices remain unchanged for at least 2 days after surgery, even for patients who demonstrated improvement at 3 months. However, worsening does occur in some patients. On the basis of the results of this study and clinical experience with the postoperative course, a selective management protocol is outlined.

Abstract
Presented in an illustrative case report and a review of the anesthetic management of obstructive sleep apnea patients. Preoperative evaluation should include a thorough airway evaluation and a comprehensive cardiovascular and pulmonary evaluation. With polysomnography, identification of the severity of sleep apnea can be idenified. Although sleep centers vary in their definitions, severe obstructive sleep apnea is diagnosed if the patient demonstrates an apnea index greater than 70 and an oxygen (O2) desaturation less than 80% with cardiovascular sequelae. Severe sleep apnea patients are at extreme risk for general anesthesia. These risks should be discussed preoperatively with the patient. Unsupervised preoperative sedation should be avoided because of the extreme sensitivity of these patients to sedatives and airway obstruction. Intraoperative management of the obstructive sleep apnea patient varies depending on the severity of the sleep apnea. Invasive monitoring may be necessary if the patient demonstrates evidence of cardiopulmonary dysfunction. With the assistance of the otolaryngologist, the anesthesiologist can formulate an approach to establishing an airway. Intraoperative opioids and sedatives should be limited. The recovery of the sleep apnea patient is extremely important and is the time when most airway emergencies occur. Extubation of the patient should occur when appropriate surgical personnel and equipment are available in case of an airway emergency. Steroids may be used to decrease the amount of airway swelling. Supplemental O2 should be used in patients who demonstrate desaturation. Opioids and sedatives should be avoided, as should other drugs that have central and sedating effects. Postoperative pain is effectively controlled with acetaminophen and topical anesthetic sprays. Postoperative monitoring for apnea, desaturation, and dysrhythmias is a necessity in sleep apnea patients.

Abstract
We performed nocturnal diagnostic polysomnography (PSG 1), PSG early after UPPP on the second to the fifth postoperative night (PSG 2) and PSG late after UPPP (PSG 3) six or more weeks after surgery, on 15 male patients with obstructive sleep-disordered breathing. On PSG 1, the A + H/I for the group was 66.6 +/- 8.8 (mean +/- SE). During non-REM sleep the A + H/I on PSG 3 (29 +/- 10) was lower than it was on PSG 2 (54.3 +/- 11.3) (p = 0.004) and lower than that on PSG 1 (70.8 +/- 10.3) (p = 0.003). Similarly, during non-REM sleep, the AI on PSG 3 (16.1 +/- 7.4) was less than that on PSG 2 (39.1 +/- 10.4) (p = 0.003) and less than that on PSG 1 (41.7 +/- 9.6) (p = 0.015). In the eight patients in whom REM sleep was recorded on all three PSGs, there was no difference with respect to A + H/I or AI. The nadir of SaO2 during non-REM sleep was higher during PSG 3 than during PSG 1 (p = 0.002), but not different from that on PSG 2. There were no differences among the three studies with respect to REM-related nadirs of SaO2; however, there was a good deal of interindividual variability across the three PSGs. In general, individuals with satisfactory amelioration of sleep-disordered breathing on PSG 2 demonstrated similar improvement on PSG 3. Patients who did not have a substantial improvement in the early postoperative period often had improvement on PSG 3, but there was a good deal of interindividual variability in this regard. We conclude that PSG within a few days following UPPP is warranted in patients with obstructive sleep-disordered breathing to determine if there has been worsening of upper airway function or oxygenation (or both) during sleep in the early postoperative period. A satisfactory result early after UPPP suggests that a late postoperative PSG is unnecessary, with savings in cost and the convenience.
