Efficacy of different methods of anesthesia on children underwent hypospadias surgery

Abstract

To assess the efficacy of different methods of anesthesia on children underwent hypospadias surgery. A total of 90 children (2-6 years old, 11.5-21.0 kg weight) with I or II grade of hypospadias based on ASA standard, who scheduled for hypospadias angioplasty, were randomly divided into 3 groups: Group I, general anesthesia combined epidural anesthesia; Group II, laryngeal mask airway under general anesthesia; Group III, laryngeal mask airway under general anesthesia combined epidural block. All children were inhaled sevoflurane to keep bispectral index value in a range from 45 and 60. The Group I adopted epidural anesthesia after intravenous induction of anesthesia; the Group II was inserted laryngeal mask after induction; the Group III was inserted laryngeal mask after induction and adopted epidural block. The anesthesia efficacy, hemodynamic changes, adverse reaction and the postoperative complications were observed in the 3 groups. Compared with the Group I or the Group II, the blood pressure and heart rate ran more smoothly in the Group III, and the postoperative agitation and incidence of adverse events were also significantly reduced (all P<0.05). The laryngeal mask airway under general anesthesia combined epidural block is a better choice for children scheduled for hypospadias angioplasty.
