Effect Of Laryngeal Tube-suction Ii On Hemodynamics And Ventilation For The Skull Reconstructive Surgery Patients

Objective To explore the effect of laryngeal tube-suction II onhemodynamics and ventilation for skull reconstructive surgery patients.Methods Select general anesthesia in60cases of reconstructivesurgery patients，using randomized controlled trials, were randomlydivided into two groups (n=30): the LTS II as a experimentalgroup,using tracheal tube as a control group.Given propofol, sufentanil, rocuronium after induction of anesthesia,place laryngeal tube-suction II or tracheal tube, use propofol, sufentanil,sevoflurane to maintain combined intravenous anesthesia, give rocuroniumto maintain muscle relaxants intermittently in the surgery.Monitor invasiveblood pressure, heart rate, pulse rate, pulse oximetry, electrocardiogram inthe surgery, measure arterial blood gas at5min before induction ofanesthesia and1h after artificial airway placement. Observe artificial airwayplacement, record the time of enrollment, the number of placement; observeand record two sets of artificial airway insertion and removal of the phase ofmean artery pressure, heart rate; observe and record the end-tidal carbon dioxide partial pressure, peak airway pressure, saturation of pulse oxygen,blood gas analysis of two groups, measure oropharyngeal leak pressure ofthe experimental group; accord anesthesia score, observe unplug the stagecough and24h after surgery complications.Results (1) Placement: time of enrollment, the number of placement,placement success rate at first attempt in the two groups was no significantdifference(P>0.05).（2）Hemodynamics: in the control group, HR after extubation1min(T6),3min (T7) increase than HR before extubation (T5)(P<0.05)； otherHR indicators was no significant difference(P>0.05). In the experimentalgroup, MAP、 HR at each time point was not statistically significant (P>0.05)； between the two groups, MAP、 HR at each point in time was notstatistically significant (P>0.05).（3）Ventilation: the ventilation in the two groups was good, PETCO2was30~40mmHg, Ppeak was14~20cmH2O, SpO2≥95%, arterial bloodgas analysis was normal. Oropharyngeal leak pressure of experimentalgroup was32.2±5cmH2O.（4）Anesthesia recovery score in two groups was not statisticallysignificant (P>0.05). Cough in disconnect stage in the two groups wasstatistically significant (P<0.05); sore throat incidence of24h after operationin the two groups was statistically significant (P<0.05).Conclusions The ventilation of laryngeal tube-suction II in skull reconstructive surgery is good，and there is no significant effect onhemodynamics.
