Randomized Controlled Trial
Continuous Intra-Incisional Bupivacaine for Postoperative Analgesia after Hip Nailing Surgery: A Randomized Clinical Trial.
The effectiveness of continuous wound infiltration (CWI) as a postoperative pain-control technique has been shown in many surgical procedures. This study investigates the effect of CWI of local anesthetic on postoperative pain control in intertrochanteric fracture patients undergoing hip nailing surgery. ⋯ CWI of bupivacaine helps better pain reduction during the early postoperative hours while it reduces opioid consumption, minimizes nausea and vomiting, and improves patient satisfaction.

Complications and critical incidents arising during anaesthesia due to patient, surgical or anaesthetic factors, may cause harm themselves or progress to more severe events, including cardiac arrest or death. As part of the 7th National Audit Project of the Royal College of Anaesthetists, we studied a prospective national cohort of unselected patients. Anaesthetists recorded anonymous details of all cases undertaken over 4 days at their site through an online survey. ⋯ Emergency (urgent and immediate priority) surgery accounted for 3454 (16%) of non-obstetric cases but 714 (42%) of complications with severe hypotension, major haemorrhage, severe arrhythmias, septic shock, significant acidosis and electrolyte disturbances all being 'common' (100-1000 per 10,000 cases). Based on univariate analysis, complications were associated with: younger age; higher ASA physical status; male sex; increased frailty; urgency and extent of surgery; day of the week; and time of day. These data represent the rates of potentially serious complications during routine anaesthesia care and may be valuable for risk assessment and patient consent.

Randomized Controlled Trial
Effects of 4 mg and 8 mg Dexamethasone Added to Intrathecal Bupivacaine on Perioperative Analgesia Among Adult Orthopedic Patients at Sodo Christian Hospital: A Prospective Cohort Study.
Background: Several adjuvant drugs have been tried to prolong spinal anesthesia block. Currently, dexamethasone appears to be effective in extending the duration of sensory block and enhancing analgesia during surgery. It is unclear, however, whether administering dexamethasone at a dose of 8 mg offers any advantages over administering it at a dose of 4 mg. ⋯ In addition, there was no significant difference (p > 0.05) in postoperative analgesic use, initial analgesia rescue time, or pain severity, as measured by the Numerical Rating Scale (NRS). The addition of dexamethasone did not result in any issues, nor was there a statistically significant difference in the onset time between the two groups. Conclusion: Dexamethasone at a dose of 4 mg extends the duration of sensory, motor, and overall analgesia in a manner similar to that of 8 mg dexamethasone with comparable durations for both the initial analgesic request and overall analgesic use.

Malignant hyperthermia (MH) susceptibility is a heritable musculoskeletal disorder that can present as a potentially fatal hypermetabolic response to triggering anesthesia agents. Genomic screening for variants in MH-associated genes RYR1 and CACNA1S provides an opportunity to prevent morbidity and mortality. There are limited outcomes data from disclosing variants in RYR1, the most common MH susceptibility gene, in unselected populations. The authors sought to identify the rate of MH features or fulminant episodes after triggering agent exposure in an unselected population undergoing genomic screening including actionable RYR1 variants. ⋯ Results demonstrate a low frequency of classic intraanesthetic hypermetabolic phenotypes in an unselected population with actionable RYR1 variants. Further research on the actionability of screening for MH susceptibility in unselected populations, including economic impact, predictors of MH episodes, and expanded clinical phenotypes, is necessary.
