Objective To realize the current situation of glove perforation during surgical operation process,and provide basis for preventing surgical glove perforation.Methods In January 2014,an investigation on glove perfo-ration was conducted among operation personnel in 9 operating rooms in a hospital,glove perforation rates,sites, causes and noticed ways were analyzed.Results A total of 2 909 person-time was investigated,147 person-time oc-curred glove perforation,person-time rate of glove perforation was 5.05%;153 of 5 818 gloves (2.63%)were per-forated,6 person-time occurred perforation of double gloves;gloves perforation rates of each specialized surgery were significantly different (χ2=87.945,P<0.001),cardiac surgery(11.84%)and plastic surgery(10.78%)had the hight perforation rates.The common sites of perforation were index finger,thumb,and middle finger,the main cause of perforation was sharp damage by stitches and devices.Most perforations were noticed intraoperatively,and seldom found postoperatively by naked eyes;gloves of different brands had different perforation rates(χ2=33.845, P<0.001).Conclusion In order to reduce and prevent the perforation during operation process,glove brands with good quality should be chosen,and measures for the prevention of glove perforation should be formulated according to the types of surgery.

Objective To compare the efficacy and side effect between Paracetamol and Tramadol Hydrochloride Tablet and Paracetamol and Dihydrocodeine Tartrate Tablet on chronic pain. Methods From October, 2013 to October, 2015, 84 patients with chronic pain were divided into group A (n=42) and group B (n=42), who took two Tramadol tablets or Dihydrocodeine Tartrate tablets, three times a day orally for five days. They were assessed with Numerical Rating Scale (NRS), and the incidence of satisfaction and side effect were in-vestigated. Results The score of NRS decreased in both groups after treatment (t>9.402, P<0.001), and there was no significantly difference between them (t=0.461, P=0.941). No significant difference was observed in incidence of pain relief and satisfaction between two groups (χ2=0.979, P=0.323). The incidence of constipation (χ2=5.864, P=0.006) and abdominal distention (χ2=9.946, P=0.002) were less in group A than in group B, but the incidence of nausea was more (χ2=4.934, P=0.026), while the incidence of dizziness, vomiting and tiredness was no significantly different between two groups (χ2<1.451, P>0.061). Conclusion The analgesic efficacy is similar of both drugs, but different in side effects of gastrointestine.

Objective To investigate the treatment of symptomatic patent ductus arteriosus (PDA) in very low birth weight preterm infants. Methods From January 1, 2008 to December 31, 2010, 78 very low birth weight preterm infants (birth weight＜1500 g) were diagnosed as symptomatic PDA. Among which, 42 cases administered orally with indomethacin (0.2 mg/kg, every 12 hrs for three times) were taken as treatment group, while five cases in this group who failed to indomethacin treatment were interrupted with video-assisted thoracoscopic surgery. And 36 cases who did not receive treatment for ductus arteriosus were taken as control group. The clinical outcomes, complications and prognosis of these patients were observed. Results There were no significant differences between the gentle percentage, gestational age, diameter of ductus arteriosus, rate of complicated with heart failure, sepsis, neonatal respiratory distress syndrome and intraventricular hemorrhage of two groups (P>0.05, respectively). The ductus arteriosus closed in 33 patients of treatment group (78.6%) and in nine patients of control group (25.0%)(χ2=22.39,P=0.000). There were no significant differences in serum creatinine level and platelet count between before and after the treatment in treatment group(P>0.05). Compared with control group, the treatment group had lower incidence of intraventricular hemorrhage (z=1.167, P=0.030), shorter duration of oxygen therapy [(8.0±5.5) d vs (13.3±9.3) d, t=2.225, P=0.032] and shorter hospital stay [(39.0±7.7) d vs (43.6±10.6) d, t=2.229, P=0.029]; while the incidence of bronchopulmonary dysplasia and necrotizing enterocolitis were similar (P>0.05). The five cases of PDA who received video-assisted thoracoscopic surgery were successfully interrupted with no residual shunt left, while three of them had lung infections and one had pleural effusion, but no pneumothorax and infant death associated with surgery occurred. Conclusions Symptomatic PDA of very low birth weight preterm infants should be treated actively. Oral indomethacin was an effective and safe method to cure the PDA in these infants. Surgical ligation under video-assisted thoracoscopic surgery after failure of indomethacin treatment might be a good option.

Objective To compare the efficacy and safety of oral ibuprofen and indomethacin for the closure of patent ductus arteriosus (PDA) in preterm infants and investigate the factors affecting the effect of indomethacin.Methods Two hundred and four preterm infants with symptomatic PDA were enrolled in this retrospective study.They were divided into two groups accroding to the admission date.From Jan.1,2007 to Dec.30,2009,44 infants orally administered ibuprofen (one course:first dose was 10 mg/kg,followed by two doses of 5 mg/kg at 24 h intervals) were as ibuprofen group.From Dec.31,2009 to Jan.31,2011,160 infants orally administered indomethacin (one course:0.2 mg/kg,at 12 h and 24 h intervals for three times) were as indomethacin group.Chisquare test,t test and rank sum test were used to compare the rate of ductal closure,side effects and complications of two groups.Influence factors of indomethacin therapy were analyzed with Logistic regression.Results There were no differences of overall ductal closure rate [77.3％ (34/44) vs 70.6％ (113/160),x2 =0.757,P＞0.05],one course therapy [68.2％ (30/44) vs 63.8％(102/160),x2=0.297,P＞0.05] and two courses therapy closure rate [9.1％ (4/44) vs 6.9％(11/160),x2 =0.030,P＞0.05] between i buprofen group and indomethacin group.The incidences of oliguria [＜1 ml/(kg ? h)] and high serum creatinine (＞88 μmol/L) of indomethacin group were higher than those in ibuprofen group [21.3％ (34/160) vs 6.8％ (3/44),x2=4.841,P=0.028;26.9％ (43/160) vs 9.1％ (4/44),x2=6.156,P=0.013].Logistic regression analysis showed that small gestational age (OR=2.563,95％CI:1.099-5.976,P=0.029),neonatal respiratory distress syndrome (OR=2.407,95％CI:1.023-5.664,P=0.044)and septicemia (OR=4.575,95％CI:1.782-26.768,P=0.009) were unfavorable factors for ductal closure in preterm infants underwent indomcthacin therapy,while antenatal steroid (OR=0.530,95％CI:0.312-0.901,P=0.018) was a favorable factor.Conclusions Oral ibuprofen have the same effects as indomethacin on PDA treatment in preterm infants,but with fewer side effects on renal function in terms of urine output and serum creatinine level.Some factors such as septicemia may affect the theraputic effects.
