我院将胃切除术病人分为针刺复合硬膜外麻醉(简称针药组)和硬膜外麻醉(简称对照组)各10例进行比较

从中探讨针刺复合麻醉下的针刺镇痛的效应。两组病例系随机交替进行。故两组性别、年龄和手术时间等均相近似(病种见表1)。除麻醉医生固定外

术者、病人以及手术方式等没有特别要求

均按常规进行。方法 (一)穴位和刺激方法穴位:至阳、脊中。刺激方法:脊中穴接正极

用G6805针The effects of combined acupuncture anesthesia in subtotal gastrectomy were observed. The atients were Prandomly divided into two groups

with 10 patients in each group. Combined acupuncture anesthesia with epidural anesthesia was used in one group(acupuncture plus epidural drug

AD) and epidural anesthesia in the other(control

C). Comparison was done betwe- en the two groups. The case

the sex and age of the patient

and the du- ration of operation were similar in the two groups. Apart from the ane- sthesiologists who were regular in the study

the patients

the operators and the operative patterns were not specially selected. The puncture sites for epidural anesthesia were at T8-T9 and the ca- theters were inserted in 3 cm upwards. The mixture of 1% lidocaine and 0.15% dicaine was used. The premedicatant was sodium luminal 0.1g. A- gain

dolantin 50-75 mg or mixture of dolantin and phenergan 2 ml was injected intravenously just before the incision. The acupuncture points used in AD group were Zhiyang and Jizhong. The total dosage of anesthetic used in each patient and the dosage used per hour were 13.9 ml and 5.3 ml respectively in the AD group and 29.1 ml and 10.4 ml in the C group. There were significant differences between the two groups (P<0.01). The differences in dosage were also found in the same age grade of the two groups(P<0.01). In the AD group

the me- an dosages were 14.6 ml in patients aged 27-45 and 13.2 ml tin those aged 46-65. In the C group

they were 28.0 ml and 29.57 ml respectively. The anesthetic effects were satisfied and were similar in the two groups. Besi- des one case of degree II in the AD group

the remainders were all belong to degree I. The dose of ephedrine used in each case was 11.5 ml in AD group and 20 ml in C group. By combined acupuncture anesthesia

not only the anesthetic effect was promoted but less dose of anesthetic was required

thence raising the safe- ty and reducing the complication during the anesthesia. which is particula- rly preferable for the severely ill patient. However

so far as the spla- nchno-dragging pain

the post-operative pain

or

air exhaust from bowels is concerned

the after-effect of acupuncture anesthesia was not fully ma- nifested in the AD group. The reasons for this may be follows: 1) the a- cupuncture points being just in the area that was blocked by epidural blo- ckade; 2) the patients

the cases being free from selection and the opera- tors and the patterns of operation being free from restriction

thus

more local anesthetics being required; 3) in some cases

the induction period be- ing not achieved thereby affecting the accumulation of acupuncture stimuli and the elaboration of acupuncture effects. We believe that is the combined acupuncture anesthesia done

the acu- puncture points snould be selected in the limbic areas outside the regional block. principally

the acupuncture sensation should be maintained throug- hout the duration and the effect of acupuncture could be elaborated fu- lly.
