Surgical Closure of the Cleft Palate Has a Transient Obstructive Effect on the Upper Airway in Children.

OBJECTIVE: To prospectively investigate the occurrence of respiratory symptoms related to obstructive sleep apnea (OSA) following primary palatoplasty in children with cleft palate (CP). METHOD: Fifty-six nonsyndromic children presenting CP with a previously repaired cleft lip (CL) or without CL were assessed before and after palate repair. Twenty nonsyndromic children with isolated CL were analyzed as controls before and after lip repair. Respiratory symptoms were investigated preoperatively, and at early and late postoperative periods. Based on the parent reports of "difficulty of breathing (D), apnea events (A) and/or snoring (S) during sleep, a validated OSA index (1.42D + 1.41A + 0.71S - 3.83) was used to predict absence of OSA, possible OSA, and presence of OSA, at the 3 periods analyzed. RESULTS: Screening for OSA showed that the CP group exhibited an increased mean index at the early postoperative assessment, suggesting "possible OSA," and a higher frequency of snoring at the early and late postoperative assessments, as compared to the CL group (P < .05). Sleep apnea events were not reported. CONCLUSIONS: Surgical closure of the palate has an obstructive effect on the upper airway in the short term, causing OSA-related respiratory symptoms, mostly transient. However, the high prevalence of snoring still observed in the long term indicate that children with a palatal cleft who undergo surgical repair are at risk for OSA. The results support the conclusion that OSA is underappreciated in this population.

[Hypothermia prevention during surgery: comparison between thermal mattress and thermal blanket]. / Prevenção da hipotermia no transoperatório: comparação entre manta e colchão térmicos.

This study aimed to compare the efficiency of the thermal blanket and thermal mattress in the prevention of hypothermia during surgery. Thirty-eight randomized patients were divided into two groups (G1 - thermal blanket and G2 - thermal mattress). The variables studied were: length of surgery, length of stay in the post-anesthetic care unit, period without using the device after thermal induction, transport time from the operating room to post-anesthetic care unit, intraoperative fluid infusion, surgery size, anesthetic technique, age, body mass index, esophageal, axillary and operating room temperature. In G2, length of surgery and starch infusion longer was higher (both p=0.03), but no hypothermia occurred. During the surgical anesthetic procedure, the axillary temperature was higher at 120 minutes (p=0.04), and esophageal temperature was higher at 120 (p=0.002) and 180 minutes (p=0.03) and at the end of the procedure (p=0.002). The thermal mattress was more effective in preventing hypothermia during surgery.
