Application Of Ultrasound Guided Nerve Block Combined With General Anesthesia In Arthroscopic Operation

Objective：to explore the influence of early rehabilitation of motor nerve blockcombined with general anesthesia analgesia in shoulder arthroscopy inoperation and after operationMethods：ASA rating of I~II level arthroscopic operation in60patients,were randomly divided into general anesthesia group (group D) andnerve block combined with general anesthesia group (group F). Patientsin group D before induction of anesthesia in ultrasound-guidedinterscalene brachial plexus block combined with superficial cervicalplexus block. Local anesthetics are made with0.5%ropivacaine, first inthe patients with anterior and middle scalene muscle interscalenebrachial plexus block vertices, observation of five minutes with noadverse reaction, to the external jugular vein and the posterior border ofsternocleidomastoid midpoint junction0.5cm for superficial cervicalplexus block. Nerve block after routine anesthesia induction. Group Fpatients into custody after direct after the induction of general anesthesia. Patients in the two groups are in the depth of anesthesia maintenance,additional fentanyl dosage according to the blood pressure, to judge thechange of heart rate. Records of patients with T0before induction ofanesthesia, T1after intubation, T2after extubation, postoperative twohours T3some time point of the mean arterial pressure (MAP), heart rate(BP). Using a visual analogue score (visual analogue, Scale, VAS)[ColeB, Finch E, Gowland C, et al. Visual Analogue Scale.In:PhysicalRehabilitation Outcome Measures [M].Canada Communication GroupPublishing,1994.80] on the pain of the patients were assessed. Recordsof patients with operation time, anesthesia time and dosage of fentanylin operation. Record the postoperative patient-controlled analgesia pumpafter pressing times. The quality of early rehabilitation therapy inpatients with postoperative score and anesthesia related adverse reaction.Result:1.Patient sex, age, weight, preoperative ASA classification andMAP, RP (p>0.05) had no significant difference in operation time,anesthesia time had no significant difference, no statistical significance(p>0.05)2.intraoperative and postoperative two hours hemodynamicchanges compared with D group, F group were more stablehemodynamics, blood pressure and heart rate were significantdifferences, with statistical significance (p<0.05)3.Intraoperativesufentanil dose and postoperative analgesia pump press numbers, F group than that in the D group, there was statistically significant (p<0.05)4.Visual analogue scale (VAS) of:F group was lower than that of Dgroup had statistical significance (p<0.05)Conclusion:ultrasound guided nerve block combined with general anesthesiafor shoulder arthroscopy operation, not only can better maintain stablehaemodynamics during the operation, but also can reduce the anestheticdosage, improve the comfort degree of patients, more effective andlasting analgesic, with early rehabilitation exercise for patients afteroperation. Compared with general anesthesia of tradition, to meetoperation needs at the same time, prolongs the analgesia time, greatlyreducing the operation wound pain to patients, is worthy of promotion.
