Abstract
Purpose The aim of this study is to evaluate operating conditions during general anesthesia
with or without neuromuscular blocker (NMB) in patients undergoing percutaneous internal
ring suturing (PIRS).
Materials and Methods In this study, 40 patients, with American Society of Anesthesiologists I and II between
the ages of 1 and 12 years, were randomly assigned to two groups to receive muscle
relaxant with endotracheal tube (ETT) (ETT group) or without muscle relaxant with
supreme laryngeal mask airway (sLMA) (LMA group). Anesthesia was maintained with sevoflurane
in oxygen (Fio
2 0.3–0.5), thiopental sodium, fentanyl, and rocuronium in ETT group. In LMA group,
same protocol was used without rocuronium. Heart rate, blood pressure, peak airway
pressure, end-tidal carbon dioxide (EtCO2), and Spo
2 were recorded before and during pneumoperitoneum maintained at a pressure of 8 to
10 mm Hg. Duration of surgery, recovery time, anesthetic time, and grade of quality
view were also recorded. Airway problems (cough, hoarseness, laryngospasm, and aspiration)
were recorded.
Results In LMA group, there was a statistically significant reduction in recovery time versus
ETT group (11.6 ± 4.08 vs. 17.15 ± 5.32 minutes; p = 0,001). There were no statistically significant differences grade of quality view
between the two groups (p = 0.548). There were no statistically significant differences in oxygen saturation
(Spo
2), peak airway pressure, and EtCO2 between the two groups before or during insufflation (p > 0.05). Postoperative airway complications were significantly more prevalent in
the ETT group. There was no case of inadequate ventilation, regurgitation, or aspiration
recorded.
Conclusion sLMA is safe and suitable alternative to ETT and NMB is not necessary in general
anesthesia with sLMA, pediatric patients undergoing laparoscopic hernia repair with
PIRS.
