Effect of carbon dioxide pneumoperitoneum on hemodynumics in patients with different operation / 中国医师进修杂志

ABSTRACT

ObjectiveTo investigate the influence of carbon dioxide pneumoperitoneum,posture on blood pressure,heart rate (HR),pulse oxygen saturation (SpO2) of laparoscopic cholecystectomy (LC)and gynecologic surgery (LP) patients.MethodsTwelve LC patients (LC group)and 13 LP patients(LP group) with ASA Ⅰ - Ⅱ were selected.Anesthesia and muscle relaxation were maintained by propofol,fentanyl,enflurane,atracurium and the systolic pressure (SBP),diastolic pressure (DBP),HR,SpO2 was recorded in the following timesbefore anesthesia(T0),immediately after inflation (T1),after position adjustment (after 10 win inflation ) (T2),after 30 min inflation ( T3 ),after deflation (the end of operation)(T4).Results The SBP and DBP at T1,T2,T3 [SBP(138.75 ± 13.22),(140.42 ± 15.88),(138.67 ±16.35) mm Hg( 1 mm Hg =0.133 kPa) ; DBP(94.42 ± 5.76),(96.25 ± 8.26),(90.42 ± 7.36) mm Hg] was higher than that at T0[SBP( 135.50 ± 15.31 ) mm Hg;DBP(83.58 ± 6.70) mm Hg] in LC group(P＜ 0.01 ).The SBP and DBP at T2,T3 [SBP(136.76 ± 12.55),(136.85 ± 13.22) mm Hg;DBP(88.38 ±6.54),(87.23 ± 6.34) mm Hg ] was higher than that at T0 [ SBP( 132.52 ± 10.11 )mm Hg; DBP(74.61 ± 5.23 )mm Hg] in LP group (P ＜ 0.05 ).There was no significant difference in HR,SpO2 between T0 and the other points in two groups (P ＞ 0.05).ConclusionThe hemodynamic changes have no significant difference between LC and LP;but compared with preoperative,the hemodynamic changes have significant difference after inflation.
