Clinical, nociceptive and psychological profiling to predict acute pain after total knee arthroplasty.
Pre-operative identification of high-pain responders for acute pain after total knee arthroplasty (TKA) could lead to targeted analgesic trials and individualized analgesic strategies to improve recovery and potentially reduce the risk of persistent post-surgical pain. The aim of this study was to use simple clinical tests and questionnaires to identify predictive nociceptive and psychological factors for acute post-TKA pain. ⋯ Pre-operative widespread pressure pain hypersensitivity and pain catastrophizing are predictive of moderate severe post-TKA pain. If validated in a larger population, the clinically applicable tests should be considered in future interventions aiming to minimize post-operative pain in high-risk patients.

Comparative Study Observational StudyNorepinephrine reduces arterial compliance less than phenylephrine when treating general anesthesia-induced arterial hypotension.
During general anesthesia, arterial hypotension is frequent and may be an important contributor to perioperative morbidity. We assessed the effect of a 5 μg bolus of Norepinephrine (NA) when compared with 50 μg bolus of Phenylephrine (PE) administered to treat hypotension during maintenance anesthesia, on MAP, derived cardiac output and arterial stiffness parameters. ⋯ This study suggests that 5 μg of NA administered as a bolus in a peripheral venous line could treat general anesthesia-induced arterial hypotension with a smaller decrease in SV and arterial compliance when compared to PE.

Pharmacokinetics after a single dose of naloxone administered as a nasal spray in healthy volunteers.
There is increasing interest in the use of intranasal naloxone to reverse adverse opioid effects during management of procedural pain in children and in adults after overdose. There are limited data on the pharmacokinetics of intranasal naloxone so in this study we aimed to detail the pharmacokinetic profile of the commercially marketed injectable solution of naloxone 0.4 mg/ml when administered as an intranasal spray. ⋯ Our results show a faster uptake of intranasal naloxone to maximum concentration compared with previous studies although with a marked variation in maximum concentration. The findings are consistent with our clinical experience of the time profile for reversing the effects of sufentanil sedation in children.

The relation between skin conductance responses and recovery from symptoms of PTSD.
The purpose was to investigate if potentially stressful reminders of the intensive care unit (ICU) stay influenced variability in transient skin conductance responses, and whether such changes were associated with post-traumatic stress symptoms (PTSS), and development of symptoms over time. ⋯ A low variability, or reactivity in skin conductance responses to situational cues could imply a risk of developing, or not being able to recover from, symptoms of PTSD in women. As such, the measurement could be used to predict this risk in women. However, further studies are necessary to evaluate this area of application.

Observational StudyFeasibility of an endotracheal tube-mounted camera for percutaneous dilatational tracheostomy.
Percutaneous dilatational tracheostomy (PDT) in critically ill patients is often led by optical guidance with a bronchoscope. This is not without its disadvantages. Therefore, we aimed to study the feasibility of a recently introduced endotracheal tube-mounted camera (VivaSight™-SL, ET View, Misgav, Israel) in the guidance of PDT. ⋯ Percutaneous dilatational tracheostomy with optical guidance from a tube-mounted camera is feasible. Further studies comparing the camera tube with bronchoscopy as the standard approach should be performed.
