Randomized Controlled Trial
Diagnostic accuracy of home-based monitoring system in morbidly obese patients with high risk for sleep apnea.
No previous studies have validated the use of portable monitoring (PM) for the diagnosis of obstructive sleep apnea (OSA) in morbidly obese individuals. Our aim was to investigate the accuracy of PM for detecting respiratory events in morbidly obese patients that will be undergoing bariatric surgery. ⋯ PM is an efficacious method for diagnosing OSA in obese patients who have a high clinical probability of the disease. The method displays good sensitivity and specificity in severe cases; nevertheless, the high rate of data loss must be taken into account.

Randomized Controlled Trial
Intranasal nicotine increases postoperative nausea and is ineffective in reducing pain following laparoscopic bariatric surgery in tobacco-Naïve females: a randomized, double blind trial.
Nicotine is a known analgesic. Our primary aim was to test the hypothesis that intranasal nicotine administered intraoperatively reduces the need for postoperative opioids. The secondary outcomes included evaluation of both postoperative pain and nausea and vomiting (PONV). ⋯ Intraoperative intranasal nicotine did not exhibit opioid-sparing effect in nonsmoking bariatric female patients. Despite antiemetic prophylaxis, the use of nicotine was associated with the higher frequency of the use of rescue antiemetics in PACU.

Does epidural morphine loading in addition to thoracic epidural analgesia benefit the postoperative management of morbidly obese patients undergoing open bariatric surgery? A pilot study.
Insufficient data exist regarding postoperative thoracic epidural analgesia for morbidly obese patients undergoing open bariatric surgery. This study evaluated the effectiveness of morphine loading in a postoperative thoracic epidural analgesic regimen of patient-controlled epidural analgesia (PCEA) with levobupivacaine combined with continuously administered epidural morphine in this patient group. ⋯ Thoracic PCEA with 0.1 % levobupivacaine combined with continuous epidural morphine administration of 0.2 mg/h without morphine loading is an effective postoperative analgesic regimen that provides adequate pain control, early ambulation, and early return of bowel function in superobese patients, particularly those with OSA.

Randomized Controlled Trial Multicenter Study
Buttressing the staple line: a randomized comparison between staple-line reinforcement versus no reinforcement during sleeve gastrectomy.
Bariatric surgery is recommended for Indian patients with body mass index (BMI) >32.5 kg/m(2) with at least one comorbidity and >37.5 kg/m(2) without a comorbidity. In laparoscopic sleeve gastrectomy, bleeding and leakage from the staple line are common post-operative events. Peri-Strips Dry® with Veritas® (PSD-V) is used in staple-line reinforcement. ⋯ Surgical time was shorter in patients who received PSD-V (58.8 vs 72.8 min; p=0.0153), and fewer patients required hemostatic clips and/or sutures (10/51 [19.6 %] vs 33/49 [67.3 %] patients; p<0.0001). Fewer patients in the PSD-V than the control group experienced adverse events (2/51 [3.9 %] vs 5/49 [10.2 %] patients). The use of PSD-V reduced the incidence and severity of staple-line bleeding and was associated with a reduction in surgical time compared with no staple-line reinforcement.

Randomized Controlled Trial
Perioperative fluid guidance with transthoracic echocardiography and pulse-contour device in morbidly obese patients.
In bariatric surgery, non- or mini-invasive modalities for cardiovascular monitoring are addressed to meet individual variability in hydration needs. The aim of the study was to compare conventional monitoring to an individualized goal-directed therapy (IGDT) regarding the need of perioperative fluids and cardiovascular stability. ⋯ In morbidly obese patients suspected of being hypovolemic, increased cardiovascular stability may be reached by preoperative rehydration. The management of rehydration should be individualized. Additional invasive monitoring does not appear to have any effect on outcomes in obesity surgery.
