Review Comparative StudyA comparison of non-endoscopic and endoscopic adhesiolysis of epidural fibrosis.
Low back and leg pain may be due to many causes, one of which is scarring in the epidural space. Epidural scarring may provoke this pain for many reasons: nerves may be trapped by scars, while veins in the epidural space press down upon the nerves and become enlarged, putting pressure on the nerves. ⋯ A search of the MEDLINE and Embase databases was conducted for the period between 1970 and 2014 using the search terms "adhesiolysis", "lysis of adhesions", "epiduroscopy", "epidural neuroplasty", "epidural adhesions", "radiofrequency lysis adhesion" and "epidural scar tissue" in order to identify articles relevant for this review. The purpose of this review is to describe the effectiveness and complications present in a comparison of non-endoscopic, endoscopic and pulsed radiofrequency endoscopic procedures in lysis of adhesions in epidural fibrosis.

Comparative StudyA comparison of BIS recordings during propofol-based total intravenous anaesthesia and sevoflurane-based inhalational anaesthesia in obese patients.
Intraoperative awareness is a rarely occurring phenomenon. Obesity is considered as one of the factors increasing the probability of intraoperative awareness due to problems with the dosing of anaesthetics. In a randomized prospective study we compared bispectral index (BIS) recordings during propofol-based total intravenous anaesthesia (TIVA) and sevoflurane-based inhalation anaesthesia in morbidly obese patients as a sign of possible intraoperative awareness. ⋯ Although the incidence of BIS > 60 are very common in obese patients, true awareness during anaesthesia infrequent in this group of patients despite the type of anaesthesia, whether intravenous or inhalation.

Randomized Controlled TrialEffect of preoperative intravenous oxycodone administration on sufentanil consumption after retroperitoneal laparoscopic nephrectomy.
The aim of this study was to evaluate the efficacy of preoperative intravenous oxycodone administration on postoperative sufentanil consumption in patients undergoing retroperitoneal laparoscopic nephrectomy. ⋯ Preoperative intravenous oxycodone can reduce postoperative cumulative sufentanil consumption and postoperative pain intensity without an increase in side effects.

ReviewEarly severe acute respiratory distress syndrome: What's going on? Part I: pathophysiology.
Severe acute respiratory distress syndrome (ARDS, PaO₂/FiO₂ < 100 on PEEP ≥ 5 cm H₂O) is treated using controlled mechanical ventilation (CMV), recently combined with muscle relaxation for 48 h and prone positioning. While the amplitude of tidal volume appears set < 6 mL kg⁻¹, the level of positive end-expiratory pressure (PEEP) remains controversial. This overview summarizes several salient points, namely: a) ARDS is an oxygenation defect: consolidation/ difuse alveolar damage is reversed by PEEP and/or prone positioning, at least during the early phase of ARDS b) ARDS is a dynamic disease and partially iatrogenic. ⋯ Therefore, in early severe diffuse ARDS, this review argues for a combination of a high PEEP (preferably titrated on transpulmonary pressure) with spontaneous ventilation + pressure support (or newer modes of ventilation). However, conditionalities are stringent: upfront circulatory optimization, upright positioning, lowered VO₂, lowered acidotic and hypercapnic drives, sedation without ventilatory depression and without lowered muscular tone. As these propositions require evidence-based demonstration, the accepted practice remains, in 2016, controlled mechanical ventilation, muscle relaxation, and prone position.

Case ReportsIntra-abdominal hypertension complicating pancreatitis-induced acute respiratory distress syndrome in three patients on extracorporeal membrane oxygenation.
Severe acute pancreatitis is associated with sever multiorgan failure from 15 to 50%, depending on the series. In some of these patients, conventional methods of ventilation and respiratory support will fail, demanding the use of extracorporeal membrane oxygenation (ECMO). Abdominal compartment syndrome is potentially harmful in this cohort of patients. We describe the successful treatment of three patients with severe acute pancreatitis who underwent respiratory ECMO and where intra abdominal pressure was monitored regularly. ⋯ Monitoring intraabdominal pressure is a valuable adjunct to decision making while caring for these high-risk critically ill patients.
