Unexpectedly low oxygen saturation in a child with a variant hemoglobin.

We report a child with an unexpected low saturation reading despite normal values having been recorded soon after birth. A family history of Rothschild hemoglobin variant affecting the father was obtained. Saturation values improved with oxygen and anesthesia was uneventful.

Volatile anesthesia for a child with LPIN1 gene mutation and recurrent rhabdomyolysis.

We report the case of a boy with LPIN1 gene mutation presenting for adenotonsillectomy who was successfully managed with preoperative saline and glucose infusion followed by balanced anesthesia including sevoflurane. The anesthetic planning is described as there is no modern literature to guide the perioperative management of these children.

Delivery of sevoflurane using a neonatal ventilator.

Background: Most anesthetic ventilators are designed to cope with a wide range of patient sizes and may lack precision at the lowest end of the minute volume scale. Neonatal intensive care ventilators on the other hand are designed specifically for this patient group, but are not able to deliver volatile anesthesia.

Aims: We aimed to adapt the neonatal ventilator currently in use in our institution to deliver sevoflurane by incorporating a vaporizer and a scavenging system.

The effect of convective heating on evaporative heat loss in anesthetized children.

Background: Convective warming is effective in maintaining core temperature under anesthesia. It may increase evaporative water loss (EWL). If significant, further investigation of warming modifications to minimize this impact would be warranted.
