[Comparison and superiority of streamlined liner of the pharynx airway to laryngeal mask airway or tracheal tubes for gynecological laparoscopy].
OBJECTIVE
To compare the variations of hemodynamics or respiratory parameters and postoperative complications incidence in gynecological laparoscopy to perform Laryngeal Mask Airway (LMA), Streamlined Liner of the Pharynx Airway (SLIPA) or Tracheal Tube (TT) and to appraise the safety or superiority SLIPA in gynecological laparoscopy.


METHODS
90 patients as ASA I-II grade for gynecological laparoscopy to divide randomly into three groups (n = 30): SLIPA group(S), LMA group(L), TT group(T). Patients were intubated with SLIPA, LMA or TT respectively after general anesthesia induction. Record and count baseline or variable values on heart rate, mean arterial pressure, peak inspiratory pressure, flat inspiratory pressure, airway compliance, airway resistance as pre- and post-intubation. To observe intra- and post-complications on backflow or aspiration, airway shifting, oral mucosa damage, cough or expectoration, pharyngodynia, trachyphonia and to appraise patient's comfort as extubation.


RESULTS
S or L group is more stable than T on hemodynamic (P < 0.05) during intubation, S group is more stable than L or T group on respiratory parameters (P < 0.05). Intraoperative incidences are significantly lower in S group than L group on backflow or aspiration, airway shifting or oral mucosa damage (P < 0.05), postoperative incidences are significantly lower in S group than L or T group on pharyngodynia, trachyphonia or cough or expectoration (P < 0.05). In addition, extubation comfort degree is better to patient as resuscitation (P < 0.05).


CONCLUSIONS
SLIPA are safely or conveniently applicable in gynecological laparoscopy. It impacts little on variations of hemodynamics or respiratory parameters after general anesthesia and reduces intra- or post-operative complications significantly compared to L or T group, increases patient's comfort as extubation. SLIPA is superior to other two on clinical applications.
