"Locked" or dislocated temporomandibular joint (TMJ) is a common problem in emergency medicine. Like many other joint dislocations, the repositioning of the joint can be facilitated by conscious sedation and muscular relaxation. Propofol is a useful agent for use in the emergency department because of its extremely short half-life, its antiemetic properties, and its safety record. We report two cases of locked TMJ that were repositioned under sedation with propofol. We review methods for repositioning the locked TMJ and review appropriate agents for sedation and muscular relaxation.

A man in his late 50s was referred by a speech and language therapist for consideration of a palatal lift prosthesis (PLP) to improve his speech intelligibility. He presented with hypokinetic dysarthria characterised by reduced loudness, breathy voice and hypernasality. The patient had a diagnosis of progressive muscular dystrophy and mobilised in a motorised wheelchair.

Objectives: Skeletal muscle wasting is a common occurrence in critical illness, often resulting in intensive care unit (ICU)-acquired weakness. This study aims to identify clinical factors associated with muscle decay in mechanically ventilated critically ill children. Utilizing point-of-care ultrasound, a noninvasive and cost-effective tool, we assess muscle decay through ultrasound of the quadriceps femoris.

Purpose: The aim of this study was to compare the effect of a pressure-controlled strategy allowing non-synchronised unassisted spontaneous ventilation (PC-SV) to a conventional volume assist-control strategy (ACV) on the outcome of patients with acute respiratory distress syndrome (ARDS).
Methods: Open-label randomised clinical trial in 22 intensive care units (ICU) in France. Seven hundred adults with moderate or severe ARDS (PaO/FiO < 200 mmHg) were enrolled from February 2013 to October 2018.

Background: Pulsed field ablation (PFA) is a novel technology for catheter-based atrial arrhythmia treatment. Evidence of its application for ventricular arrhythmia ablation is still limited. In this study, we describe the feasibility and efficacy of focal PFA for premature ventricular contraction (PVC) ablation.

Article Synopsis
- Fospropofol disodium is a new sedation drug that may offer better effects than traditional propofol, specifically for elderly patients undergoing same-day bidirectional endoscopy.
- The study involves 256 elderly participants, split evenly between fospropofol and propofol groups, to compare sedation success rates, how quickly sedation is achieved, and patient recovery times.
- Researchers aim to determine if fospropofol is as effective and safe as propofol, with hopes of establishing it as a preferred option for sedation in these medical procedures.
