Comparison of the streamlined pharynx airway liner and tracheal intubation in pediatric laparoscopic hernia surgery

Abstract

Objective To observe the feasibility and safety of the SLIPATM in pediatric laparoscopic hernia surgery. Methods Eighty pediatric patients, who were scheduled to undergo laparoscopic hernia surgery(aged 3-12 y, ASA Ⅰ or Ⅱ), were randomly divided into two groups: SLIPATM group(S group) and tracheal intubation group(T group). Each group had forty patients. HR, SBP and DBP were recorded on time points of before anesthesia induction(T0), before insertion of SLIPATM or tracheal tube(T1), 1 min after the insertion of SLIPATM or tracheal tube(T2), and 1 min after extraction of SLIPATM or tracheal tube(T3). In addition, complications such as cough, hoarseness, pharyngalgia, dysphagia, bleeding and aryngospasm were also recorded after the extraction of SLIPATM or tracheal tube. Results There were totally seventy nine patients enrolled, including thirty nine patients in S group and forty in T group. At T2-T3, the HR, SBP, DBP of S group were significantly lower than T group(P 0.05). After extraction of SLIPATM or tracheal tube, five of the thirty nine patients coughed and four of the thirty nine patients had hoarse throats in S group while fifteen of the forty patients coughed and twelve of the forty patients had hoarse throats in T group. The incidences of cough and hoarseness in S group were significantly lower than the incidences happened in T group(P<0.05). However, there was no statistically difference at the incidence of complications such as pharyngalgia, dysphagia, bleeding and laryngospasm between the two groups. Conclusions SLIPATM has fewer effects on pediatric hemodynamics and lower complication incidence than the incidence of tracheal intubation. Therefore, it can be safely applied in pediatric laparoscopic hernia surgery. Key words: Laryneal mask; Tracheal intubation; Therapeutic laparoscopy; Herniorrhaphy
