目的 分析四川大学华西医院麻醉性镇痛药应用的现状及趋势，并行客观评价。 方法 对2008年－2010年四川大学华西医院麻醉性镇痛药品的种类、用量、金额、用药频度等进行归类统计、比较和分析。 结果 住院部使用麻醉药品的用量及金额呈上升趋势。临床应用以芬太尼类居首。新型麻醉药品的应用也有上升趋势。 结论 麻醉性镇痛药的应用基本合理，但创建无痛医院仍需进一步完善，并提交合理用药水平。
目的 研究环氧合酶-2抑制剂药物的应用状况和发展趋势，为临床合理、有效、经济地选用药物提供科学依据。 方法 采用金额排序和用药频度（DDDs）、日均费用（DDC）方法，对四川大学华西医院2008年－2010年环氧合酶-2抑制剂药物的临床应用情况进行统计分析。 结果 2008年－2010年间，该院环氧合酶-2抑制剂药物的应用数量和销售金额呈逐年上升趋势，其中选择性环氧合酶-2抑制剂药物的用量增幅较大，非选择性环氧合酶-2抑制剂药物用量呈下降趋势。 结论 该院环氧合酶-2抑制剂药物临床应用合理，选择性环氧合酶-2占主导地位，有较好的发展前景。
Objective To study the causes of abdominal distension in patients with hepatocellular carcinoma (HCC) after laparoscopic hepatectomy, and to explore the corresponding treatment countermeasures. Methods A total of 186 patients with HCC were treated by laparoscopic hepatectomy in our hospital from September 1, 2018 to August 31, 2020. Demographic characteristics [age, gender, body mass index (BMI), liver cirrhosis, child-Pugh classification of liver function], operative time, hilar occlusion time, intraoperative blood loss, scope of hepatectomy, postoperative visual analogue scale (VAS) score and serological indexes (hemoglobin, serum albumin, white blood cell count, platelet count, serum potassium level) were collected retrospectively. The occurrence of postoperative abdominal distension was observed, and the patients were divided into abdominal distension group and non abdominal distension group. The independent influencing factors of abdominal distension after laparoscopic hepatectomy were analyzed, and the corresponding treatment countermeasures were discussed. Results A total of 138 patients developed varying degrees of abdominal distension after operation (74.19%), including 45 cases of mild abdominal distension, 53 cases of moderate abdominal distension, and 40 cases of severe abdominal distension. They were all included in the abdominal distension group, and the occurrence time of abdominal distension was mainly 1-5 days after operation. Forty-eight patients (25.81%) had no abdominal distension after operation and were included in the non-abdominal distension group. Univariate analysis results show that: the proportion of patients with abdominal distension combined with liver cirrhosis was significantly higher than that of the non-abdominal distension group (47.10% vs. 25.00%, P=0.007), the operative time [(143.54±23.48) min vs. (129.45±24.51) min, P=0.001], hilar occlusion time [(18.02±8.12) min vs. (15.38±7.28) min, P=0.048] were significantly longer than those of the non-abdominal distension group, the postoperative VAS score was significantly higher than that of the non-abdominal distension group [5.12±1.14 vs. 4.47±1.05, P=0.004], and the serum potassium level was significantly lower than that of the non-abdominal distension group [(3.12±0.38) mmol/L vs. (3.67±0.42) mmol/L, P＜0.001]. Multivariate unconditional logistic regression analysis showed that patients with liver cirrhosis [OR=1.520, 95%CI (1.104, 2.093), P=0.010], serum potassium level ＜3.40 mmol/L [OR=1.684, 95%CI (1.203, 2.357) , P=0.002], operative time ＞136 min [OR=1.842, 95%CI (1.297, 2.616) , P=0.001], hilar occlusion time ＞16.7 min [OR=1.492, 95%CI (1.047, 2.126) , P=0.027], VAS score ＞5 [OR=1.498, 95%CI (1.021, 2.198), P=0.039] were independent risk factors of abdominal distension after laparoscopic hepatectomy. Conclusions The risk factors of abdominal distension after laparoscopic hepatectomy were liver cirrhosis, serum potassium level ＜3.40 mmol/L, operative time ＞136 min, hilar occlusion time ＞16.7 min and VAS score ＞5. More attention should be paid to high-risk patients and effective treatment measures should be taken in time to reduce the risk of abdominal distension after surgery. For patients with abdominal distension, we should take effective measures to alleviate the symptoms of abdominal distension and promote the recovery of patients with abdominal distension.
