Effect of electroacupuncture at different time points on postoperative urination function in patients with mixed hemorrhoids surgery / 中国针灸

OBJECTIVE@#To observe the effect of preoperative, intraoperative and postoperative electroacupuncture (EA) intervention on postoperative urination function in patients with mixed hemorrhoid surgery.@*METHODS@#A total of 240 patients with mixed hemorrhoid surgery under lumbar anesthesia were randomly divided into an EA preconditioning group (group A, 60 cases, 9 cases dropped off), an intraoperative EA group (group B, 60 cases, 4 cases dropped off), a postoperative EA group (group C, 60 cases, 6 cases dropped off), and a non-acupuncture group (group D, 60 cases, 3 cases dropped off). In the groups A, B and C, EA was exerted at Zhongliao (BL 33) and Huiyang (BL 35) , with disperse-dense wave, 4 Hz/20 Hz in frequency, and lasting 30 min, at 30 min before lumbar anesthesia, immediately after lumbar anesthesia and 6 h after surgery, respectively. No EA intervention was performed in the group D. The postoperative urination smoothness score in each group was observed 24 h after surgery. The first urination time, first urination volume, urine residual volume after first urination were recorded, and incidence of indwelling catheterization, postoperative visual analogue scale (VAS) score, number of remedial analgesia, and the incidence of postoperative nausea and vomiting were observed in each group.@*RESULTS@#In the groups A, B and C, the postoperative urination smoothness scores were superior to the group D (P<0.05), and the time of first urination was earlier than the group D (P<0.05). In the group C, the time of first urination was earlier than the group A and the group B (P<0.05), the first urination volume was higher than the group D (P<0.05), and the urine residual volume after first urination was lower than the group D (P<0.05). There was no significant difference in the incidence of indwelling catheterization and postoperative nausea and vomiting among the 4 groups (P>0.05). The VAS scores of the group A, B and C were lower than that in the group D (P<0.05), and the number of remedial analgesia cases was lower than that in the group D (P<0.05).@*CONCLUSION@#EA intervention could promote the recovery of urination function and relieve postoperative pain in patients with mixed hemorrhoids surgery. Early postoperative EA intervention is more conducive to the recovery of urination function.

A color test for rapid screening of gamma-hydroxybutyric acid (GHB) and gamma-butyrolactone (GBL) in drink and urine / 法医学杂志

OBJECTIVE@#A rapid color test for screening gamma-hydroxybutyric acid (GHB) and its precursor gamma-butyrolactone(GBL) was investigated in drink and urine samples.@*METHODS@#In an acidic solution, GHB was converted to GBL, which reacted with hydroxylamine hydrochloride in presence of sodium hydroxide, forming hydroxamate. A purple complex was formed when hydroxamate reacted with ferric chloride in acidic condition.@*RESULTS@#Detection limit concentrations of GHB in drinks were between 0.5-2 mg/mL, less than the popular abuse concentrations of GHB. This method was usable for urine, with detection limit concentration 0.5 mg/mL. Interferences of common organic solvents and narcotics and depressants were surveyed.@*CONCLUSION@#This method is simple, safe, and rapid; it facilitates rapid screening of GHB and GBL in clinic and forensic laboratories.

Clinical study on acupoint-injection combined with epidural analgesia for labour / 中国基层医药

Objective To discuss whether the separating block of sensory nerve with acupoint-injection and epidural analgesia by ropivacaine during labour.Methods Ninty full term primigravidae with ASAⅠ～Ⅱwere randomly divided into 3 groups:group E(n = 30),group C(n = 30)and group A(n = 30).When the external cervi- cal os was dilated to 3cm,group A:acupiont-injection to Ci Liao;group E:epidural analgesia with 0.075% ropiva- caine and fentanyel 2?g/ml;group C:combining group A and group E except fentanyel 2?g/ml.Level of pain(VAS scores),degree of sensory and motor block,the mode of delivery,the progress of labour and side effects were recorded and compared.Results The level of pain(VAS scores)in group A was higher than that of group C and group E,and there were no significant differences in group C and group E,Bur there were some side effects discovered in group E. There was no significant differences of the mode of delivery in the groups.Conclusion The method that acupoint- rejection combined with epidural analgesia by 0.075% ropivacaine is effective and has no side effects for labour.
