High-energy tibial plateau fractures associated with severe soft tissue injury are difficult to manage. The risk of wound complications following open reduction and internal fixation is notably high owing to extensive soft tissue dissection. Alternatively, application of hybrid external fixator minimizes soft tissue dissection and provides adequate fracture stabilization to allow early range of motion and correction of any mal-alignment. With this technique, soft tissue complications particularly surgical site infections are expected to be significantly reduced. This prospective study aims to determine the effectiveness of a modified hybrid external fixator in the management of high-energy tibial plateau fractures. Thirty-three patients with high-energy Schatzker V and VI tibial plateau fracture with severe soft tissue injury precluding formal open reduction were enrolled into the study. The fixator was a construct combining the Ilizarov ring with a monolateral external fixator. The results-bony union, range of motion, and associated complications of the treatment-were assessed. All fractures united within an average time of 14 weeks. Neither loss of reduction nor surgical site wound breakdown/osteomyelitis was noted. Eight patients developed superficial pin track infection and one septic arthritis of the knee joint. Hybrid external fixation is a safe option for complex high-energy tibial plateau fractures by simultaneously providing adequate fracture stabilization and protection of soft tissue healing to achieve bony union. The complication is mainly related to pin tract infection.
Training exposure and confidence level among medical officers: Does an Emergency Physician make a difference?

The training of emergency medical officers has always been informal. Only recently, the presence of emergency physician may have a positive influence in their training and development. This study aims to determine the effect of Emergency Physician (EP) presence on the training exposure and confidence level of medical officers in their practice.
Fulltext Intravenous ketamine is as effective as midazolam/fentanyl for procedural sedation and analgesia in the emergency department

PMID: 22111446

The study compared the effectiveness of ketamine and midazolam/fentanyl as procedural sedation and analgesia agents for reduction of fractures and dislocated joints. Forty-one adult patients were enrolled by convenience sampling. They were randomized to receive ketamine or midazolam/fentanyl. Depth of sedation, pain score, procedural outcome and memory of the procedure were documented. The ketamine group had deeper sedation, but there was no statistical difference in other variables between the two groups. Three patients in the midazolam/fentanyl group had oxygen desaturation. More adverse effects were associated with ketamine. Intravenous ketamine is as effective as midazolam/fentanyl for procedural sedation.

INTRODUCTION: Anaesthesiology is a high-demand speciality with 24-hour on-call shifts, which can lead to significant stress and impaired sleep quality among anaesthetists. Nonpharmacological interventions like acupuncture have been widely explored for stress relief. This study aims to evaluate the impact of transcutaneous electrical acupoint stimulation (TEAS) on physiological parameters, specifically heart rate variability (HRV) and sleep quality, in anaesthesiology trainees following 24-hour on-call duty.
MATERIALS AND METHODS: A total of 38 anaesthesiology trainees, following 24-hour ICU on-call shifts, were recruited for this single-centre cross-sectional clinical trial. The participants were required to complete two 24-hour on-call duties. Demographic data and baseline sleep quality assessments were collected following the first on-call duty. Upon completion of the second on-call shift, participants underwent 20 minutes of TEAS at bilateral PC6 (Neiguan), LI4 (Hegu), LR3 (Taichong), and ST41 (Jiexi) points. Heart rate variability (HRV) parameters, blood pressure, and heart rate were recorded before and after TEAS. Post-TEAS sleep quality was assessed following an overnight rest.
RESULTS: The results demonstrated a significant reduction in systolic blood pressure compared to baseline (109.5±8.9 vs 111.9±10.1 mmHg, p = 0.006), as well as a significant decrease in diastolic blood pressure (69.3±8.0 vs 70.9±9.0 mmHg, p = 0.037) and heart rate (65.8±9.2 vs 67.4±9.8 bpm, p = 0.034). There was significant improvement in all aspects of sleep quality (p < 0.001). However, no statistically significant changes were observed in heart rate variability (HRV) parameters, including high-frequency (HF) power, lowfrequency (LF) power, and the LF/HF ratio.
CONCLUSION: TEAS may offer potential benefits in managing cardiovascular stress and improving sleep quality in highstress environments, such as post-call recovery. Nevertheless, its impact on autonomic nervous system regulation, as reflected by HRV, appears limited.
