摘要: Eighteen formerly premature infants scheduled for inguinal herniorrhaphy and who were less than 51 wk postconceptional age assigned to either the general anesthesia group (GA: atropine, halothane, nitrous oxide) or spinal (SA: hyperbaric tetracaine). Twelve-hour, three-channel continuous recordings of respiratory rate (chest wall impedance), electrocardiogram (ECG), hemoglobin O2 saturation (SpO2) obtained preoperatively after surgery. These analyzed short (11-15s) long (> 15 s) apnea spells, periodic breathing, episodes oxygen desaturation bradycardia. Infants in GA had lower postoperative minimum SpO2 (68.7% +/- 11.4%) heart (79 bpm 19) SA (80.7% 9.2%, 109 30, respectively; P < 0.05) they (79.0% 13.7%, 93 31, 0.05); pre- studies did not differ. There no differences incidence central apnea. We conclude that reduces bradycardia undergoing herniorrhaphy.
