Background: Accidental awareness during general anesthesia (AAGA) is defined as an unexpected awareness of the patient during general anesthesia. This phenomenon occurs in 1%-2% of high-risk practice patients and can cause physical suffering and psychological after-effects, called posttraumatic stress disorder. In fact, no monitoring techniques are satisfactory enough to effectively prevent AAGA; therefore, new alternatives are needed.

This study is a monocentric, prospective, randomised, placebo-controlled, double-blinded study in a university hospital in France.

Purpose Of Review: The purpose of this review is to discuss the optimal use of neuromuscular blocking agents (NMBA) during ambulatory surgery, and to provide an update on the routine use of neuromuscular monitoring and the prevention of residual paralysis.
Recent Findings: The number of major surgical procedures performed in ambulatory patients is likely to increase in the coming years, following the development of laparoscopic and thoracoscopic procedures. To successfully complete these procedures, the proper use of NMBA is mandatory.
Background: The prospective observational European multicentre cohort study (POPULAR) of postoperative pulmonary complications (NCT01865513) did not demonstrate that adherence to the recommended train-of-four ratio (TOFR) of 0.9 before extubation was associated with better pulmonary outcomes from the first postoperative day up to hospital discharge. We re-analysed the POPULAR data as to whether there existed a better threshold for TOFR recovery before extubation to reduce postoperative pulmonary complications in patients who had quantitative neuromuscular monitoring (87% acceleromyography).

Methods: This observational prospective study included obese patients who required bariatric surgery and a 4-gram dose of cefoxitin as an antibiotic prophylaxis.
Background: Accidental Accidental awareness during general anesthesia (AAGA) occurs in 1-2% of high-risk practice patients and is a cause of severe psychological trauma, termed post-traumatic stress disorder (PTSD). However, no monitoring techniques can accurately predict or detect AAGA. Since the first reflex for a patient during AAGA is to move, a passive brain-computer interface (BCI) based on the detection of an intention of movement would be conceivable to alert the anesthetist.

Methods: A multicentre prospective randomised trial conducted in 21 French intensive care units (ICU) between May 2011 and February 2015 compared the efficacy and safety of 8-day versus 15-day antibiotic therapy in critically ill patients with PIAI.

Purpose Of Review: Sugammadex is a selective relaxant-binding agent that is designed to encapsulate rocuronium and chemically similar steroidal muscle relaxants such as vecuronium. This review summarizes recent information on the use of sugammadex in clinical practice.
Recent Findings: The main advantages of sugammadex when compared with conventional anticholinesterase agents are a much faster recovery time and its unique ability to reverse rapidly and efficiently, for the first time, deep levels of neuromuscular blockade.

Background: Notification of sugammadex has been supplemented with a section on hemostasis, including a longer clotting time in the first minutes following injection, without any documented clinical consequences. The objective of this observational study was to analyze the effects of sugammadex administration on routine coagulation tests and bleeding in the clinical setting.
Methods: After Institutional Review Board approval, a prospective observational study was conducted between January and December 2011.
Muscle relaxants are used in the perioperative period to aid in endotracheal intubation, facilitate surgical exposure, and in the critical care setting for prolonged relaxation. Until now, the only mechanism to reverse their effect is acetylcholinesterase inhibitors that result in excess parasympathetic activity and require the second drug to prevent this side effect. Additionally, the onset and degree of neuromuscular antagonism are often unpredictable and unreliable.

Changes in plasma viscosity (PV) are barely investigated while PV modulates functional capillary density, microcirculation and organ function. The present study evaluated the impact of 2 strategies of fluid resuscitation in hemorrhagic shock in pigs.

This study aimed to evaluate predictors of motion sickness (MS) in rally car co-drivers exposed to various accelerations.
Methods: The subjects were 85 rally co-drivers (21 women) who filled in a questionnaire investigating MS symptoms in 4 situations: 1) special stages (competition itself); 2) special stages reconnaissance; 3) reading a book in the car; and 4) rear-seat passenger.
Purpose Of Review: Sugammadex belongs to a new class of drugs termed selective relaxant binding agents and is now available for clinical use in over 50 countries. Because of its innovative mechanism of action, reversal of rocuronium or vecuronium becomes independent of the degree of residual neuromuscular blockade. Deep or intense neuromuscular blockade now can rapidly and predictably be reversed.

The performance of acceleromyography, however, has not been investigated for the setting where calibration is impossible. This study first evaluated the reliability of a single acceleromyographic train-of-four (TOF) ratio (T4/T1) to detect residual paralysis and compared it with tactile estimation of fade after double-burst stimulation and 100-Hz, 5-s tetanus.
