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 times:before 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.
ABSTRACT
Objective:To evaluate the clinical safety and effectiveness of heavy specific gravity levobupivacaine in spinal block.Method:30 selective general surgical patients of ASAⅠ～Ⅱin obstetrics and gynecology were randomly di- vided into levobupivacaine group(L group)and bupivacaine group(B group).After opening the venous channel and transfusing equilibrium liquid 30 mins,the T 4-5 space was selected as the puncture site for the epidural puncture.The 2 medicaments were injected in the rate of 0.1 ml/s respectively.Then the anesthetizing onset time,maintenance time,time of motion blockade and restoration,effect of anesthesia,variations of blood pressure and heart rate and adverse drug reac- tion were observed.Result:The onset time was 82.61?22.10 s in L group and 59.30?21.50s in B group,respectively. The variations of SBP,DBP and HR in L group were less than those in B group.There was no significant difference in the 2 groups in maintenance time,time of motion blockade and restoration and effect of anesthesia.Conclusion:Compared with bupivacaine,heavy specific gravity levobupivacaine can make the same anesthesia effect with a steadier blood circulation. The specific gravity levobupivacaine is a safe and feasible drug for spinal anesthesia.
