Hyperinflation of the laryngeal mask airway (LMA) cuff is known to be a risk factor for airway morbidity and increased leakage around the LMA. While the manufacturers' recommendation is to inflate the cuff with the maximum recommended volumes and/or to adjust the cuff pressure to <60 cmH2O, cuff pressures below 40 cmH2O have been shown to be associated with a minimal rate of sore throat and minimal leakage. However, it remains to be determined whether inflation or deflation is needed to achieve favorable pressures. Therefore, we assessed the need for cuff-volume adjustment following insertion of the LMA unchanged straight from the sterile packaging in a prospective audit. ⋯ This study demonstrates that LMAs, particularly when using small-sized LMAs or LMAs with a more rigid PVC surface, need to be deflated following insertion of the device rather than inflated to avoid cuff hyperinflation. Hence, cuff pressures should be measured routinely using a manometer to minimize potential pressure-related airway complications.

Continuous infusion of ropivacaïne: an optimal postoperative analgesia regimen for iliac crest bone graft in children.
Postoperative analgesia of iliac crest (IC) donor site can be performed by on site infiltrations of local anesthetics (LA) or morphine. Single injections or continuous infusions of LA proved their efficacy in adults, but was not reported in children. We prospectively evaluated the interest of a continuous infusion of 0.2% ropivacaïne at the IC donor site in terms of postoperative pain relief and rescue analgesics consumption. ⋯ Continuous infusion of 0.2% ropivacaïne through an IC catheter is an optimal and safe technique of regional postoperative analgesia after bone graft harvest in children.

Caudal extradural blockade is one of the most commonly performed procedures in pediatric anesthesia. However, there is little information available on variations in clinical practice. ⋯ This survey provides a snapshot of current practice and acts a useful reference for the development of enhanced techniques and new equipment in the future.
