Review Meta Analysis Comparative Study
A systematic review and meta-analysis of the i-gel(®) vs laryngeal mask airway in children.
We systematically reviewed randomised controlled trials of the i-gel® vs different types of laryngeal mask airway in children. We included nine studies. There was no evidence for differences in: rate of insertion at first attempt; insertion time; ease of insertion; or gastric tube insertion. ⋯ The relative rate (95% CI) of a good fibreoptic view through the i-gel was 1.10 (1.01-1.19), p = 0.02. There were no significant differences in the rates of complications, except for blood on the airway, relative rate with the i-gel 0.46 (0.23-0.91), p = 0.02. We concluded that the clinical performance of the i-gel and LMA was similar, except for three outcomes that favoured the i-gel.

Randomized Controlled Trial
A randomised controlled trial of ultrasound-guided transversus abdominis plane block for renal transplantation.
We conducted this study to evaluate the efficacy of a transversus abdominis plane block in reducing morphine requirements in the first 24 h after renal transplant surgery. We performed transversus abdominis plane injections under ultrasound guidance in 54 patients with either 20 ml levobupivacaine 0.5% (n = 27) or 20 ml saline 0.9% (n = 27). ⋯ In the remaining 51 patients, median (IQR [range]) morphine consumption in the first 24 h was similar in both the transversus abdominis plane group (19.4 (11.7-28.6 [0.5-49.8]) mg) and the control group (16.4 (12.0-31.0 [0.0-61.7]) mg), p = 0.94. We found that use of ultrasound-guided transversus abdominis plane block for renal transplantation did not reduce 24-h morphine requirements.
