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.

Randomized Controlled Trial Comparative StudyComparison of continuous epidural block and continuous paravertebral block in postoperative analgaesia after video-assisted thoracoscopic surgery lobectomy: a randomised, non-inferiority trial.
Video-assisted (VATS) lung lobectomy can be associated with stronger postoperative pain than is commonly believed. It is generally accepted to introduce multimodal analgaesic strategies based on regional blockade, opioids and non-steroidal anti-inflammatory drugs. However, there is still no consensus regarding the optimal regional technique. The aim of this study was to compare the analgaesic efficacy of continuous thoracic epidural block (TEA) and percutaneous continuous paravertebral block (PVB) in patients undergoing video-assisted lung lobectomy. ⋯ Postoperative pain following VATS lung resection procedures is significant and requires the application of complex analgaesic techniques. Percutaneous paravertebral block is equally effective as thoracic epidural block in providing analgaesia in patients undergoing VATS lobectomy. Paravertebral block has a better safety profile than thoracic epidural block.

Randomized Controlled Trial Comparative StudyA comparison of subhypnotic doses of propofol and midazolam during spinal anaesthesia for elective Caesarean section.
This study compared two types of sedation in pregnant women receiving subarachnoid anaesthesia for elective Caesarean section. ⋯ Midazolam and propofol induce effective and safe sedation in patients receiving subarachnoid anaesthesia for Caesarean section. Propofol appears to be more useful for Caesarean section sedation when compared with midazolam because of its shorter action, antiemetic effects and better maternal recall of foetal delivery.

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.
