Objective To observe the survival rate of reversed-flow free flap after anastomosing one venous reverse flow and to explore the change of intravenous pressure and mechanism of venous reverse flow. Methods Thefree vascularized posterior tibial flap with reversed flow was successfully established in NewZealand white rabbits.Fifteen rabbits were randomly allocated into 3 groups of 30 flaps. In group A,two vena comitans were anastomosed.In groups B and C,only onevenae comitans was anastomosed. In groups A and B,intravenous pressure was measured immediately and 30,60 and 120 minutes after anastomosing the vascular pedicle.Flap survival rate of group B was measured after two weeks. In group C, radiography of one venae comitans was observed.The diameters of posterior tibial vessels was measured on all the rabbits before anastomosing the vascular pedicle. Results The diameters of posterior tibial artery was 8.0±0.3mm and of vena comitans was 11.0±0.5 mm。The intravenous pressure of group B increased rapidly and reached its top value after about 30 minutes (P＜0.05).It then decreased and approached normal level after about 60 minutes (Pgt;0.05).The intravenous pressure was not significantly different between groups A and B in each time interval (Pgt;0.05).Two flapsresulted in avulsion,infection and necrosis.The remaining 8 flaps survived completely.Most of the radiopaque in group C flew back to the proximal tibia one hourlater. Conclusion Venous retrograde return is abundant in reverseflow free flap of anatomosing one vena comitans.The main way of venous reflux in reverseflow free flap can be through “direct incompetent valve route”.
ObjectiveTo observe and compare the efficacy and safety of intravenous thrombolysis with alteplase or urokinase in the first-ever acute ischemic stroke patients arriving at the hospital 3.5-4.5 h after onset.MethodsClinical data of patients with acute ischemic stroke treated in Shihezi People’s Hospital between January 2019 and October 2020 were prospectively collected. The National Insititutes of Health Stroke Scale (NIHSS) score on the 7th day and the 90th day, the modified Rankin Scale (mRS) score and the Blessed Behavior Scale (BBS) score on the 90th day, and symptomatic bleeding within 36 h after thrombolysis were analyzed and compared between the patients receiving alteplase threatment (the alteplase group) and the ones receiving urokinase treatment (the urokinase group).ResultsTotally 96 patients were treated with intravenous thrombolysis. Among them, 58 patients received alteplase threatment and 38 received urokinase treatment. The difference in NIHSS, mRS, or BBS scores between the two groups before treatment was not statistically significant (P>0.05). On the 90th day after treatment, the NIHSS, mRS, and BBS scores of the alteplase group were 3.59±3.73, 2.26±1.26, and 15.33±8.28, respectively, and those of the urokinase group were 5.95±4.88, 3.00±0.87, and 20.37±11.80, respectively; the differences between the two groups were all statistically significant (P<0.05). There was no significant difference in the rate of symptomatic intracerebral hemorrhage between the two groups within 36 h after treatment (P>0.05). Multiple linear regression analyses showed that the treatment method was related to the NIHSS score on the 7th day, the NIHSS score on the 90th day, the mRS score on the 90th day, and the BBS score on the 90th day (P<0.05), the history of heart disease was related to the mRS score on the 90th day (P<0.05), and the income was related to the BBS score on the 90th day (P<0.05).ConclusionFor the hyperactue ischemic stroke, the overall effect of alteplase treatment may be better than that of urokinase treatment.
Objectives To overview the systematic reviews/meta-analyses of safety of femoral nerve block (FNB) used as a postoperative analgesic technique in patients undergoing total knee arthroplasty (TKA). Methods We searched databases including The Cochrane Library, PubMed, EMbase, CNKI, WanFang Data, and VIP from inception to July, 2016. Two reviewers independently screened literature, extracted data and used AMSTAR to evaluate the methodological quality of the included studies. The major indexes used to evaluate the safety of FNB were the incidence rates of symptoms including nausea, vomiting, sedation, retention of urine, dizziness, pruritus, hypotension, falls, nenous thromboembolism and deep infection. Results A total of 12 systematic reviews/meta-analyses were included.They assessed the safety of FNB compared with local infiltration analgesia (LIA), periarticular multimodal drug injection (PMDI), epidural analgesia (EA), patient-controlled intravenous analgesia of opioids (PCA) and adductor canal block (ACB), respectively. The methodological quality of included studies were medium, with the scores between 3 to 10. The results of overview indicated that: FNB had lower incidence rates of nausea and vomiting compared with EA and PCA, but had higher than ACB. FNB had lower incidence rates of sedation and retention of urine compared with EA and PCA. FNB had lower incidence rates of dizziness compared with EA and PCA, and lower incidence rate of hypotension compared with EA. Conclusion Current evidence suggests that FNB is safer than EA and PCA. Due to the limited quantity and quality of the included studies, the above conclusions are needed to be verified by more high-quality studies.
ObjectiveTo investigate the efficacy and safety of intravenous diltiazem in controlling ventricular rate in elderly patients with atrial fibrillation. MethodWe retrospectively analyzed the clinical data of patients suffering from atrial fibrillation with rapid ventricular rate presented to the Emergency Department between January 2014 and January 2015, and found that 57 elderly patients aged over 70 were treated with intravenous diltiazem for ventricular rate controlling. We analyzed the general situation of this group of patients, the changes of heart rate and mean arterial pressure before and after the treatment, and the adverse reactions to the treatment. ResultsThe total effective rate was 92.9%, and the mean onset time was (13.3±7.3) minutes. The mean arterial pressure showed no significant difference after treatment, and the heart function showed no significant deterioration. Only 4 patients (7.0%) had symptoms of transient hypotension. ConclusionsFor elderly patients with atrial fibrillation with rapid ventricular rate, intravenous diltiazem can control the ventricular rate rapidly, efficiently, safely, and sustainably.
Abstract: Intravenous leiomyomatosis (IVL) is a rare kind of uterine myoma. It is a benign smooth muscle tumor with invading growth pattern. The tumor extends into venous channels, but rarely invades tissues. It grows along the refluxing direction of the venous channels, uterine vein, ovarian vein, and beyond the uterus, extends into the inferior vena cava till the right atrium or pulmonary arteries, resulting in intracardiac leiomyomatosis (ICL). At present, the tumor can be detected by ultrasonic waves, computer tomography and magnetic resonance imaging. The main ICL therapy is surgery which is divided into onestage operation and twostage operation in which the key is the complete tumor excision. Most sufferers have a good prognosis, but there are possibilities of recurrence. Missed diagnosis and misdiagnosis are not uncommon, because the disease is rare with hided and diversified clinical manifestations. It is fatal without special characteristics. For a better understanding of ICL, the recent research and treatment of ICL are reviewed.
ObjectiveTo investigate the effectiveness of hydrocolloid dressing in preventing peripheral phlebitis due to intravenous infusions. MethodsFrom April 1st to October 30th, 2014, 320 patients admitted in the Biliary Department of West China Hospital for parenteral nutrition were collected along with their clinical data and were randomly divided into control group and intervention group. A total of 160 patients who were allocated in the control group accepted simple dressing with 3M adhesive tape (6 cm×7 cm) at the intravenous catheter site. In contrast, hydrocolloid dressing (5 cm×7 cm) was applied at the intravenous catheter site and then covered with 3M adhesive tape (6 cm×7 cm) for the patients in the intervention group. ResultsPhlebitis rate was significantly higher in the control group (115 patients) than that in the interventions group (64 patients) (χ2=32.978, P<0.001). In addition, the severity of phlebitis was higher in the control group than that in the intervention group (Z=-4.466, P<0.001). Statistically significant difference was noted. ConclusionHydrocolloid dressing is effective in preventing and delaying the occurrence of peripheral phlebitis due to intravenous infusions.
Objective To analyze the outcome of fast track surgery after intercostal nerve block (INB) during thoracoscopic resection of lung bullae. Methods We recuited 76 patients who accepted thoracoscopic resection of lung bullae from February 2013 to March 2015. They were randomly divided into two groups: an intercostal nerve block and intravenous patient-controlled analgesia (INB+IPCA) group, in which 38 patients (30 males, 8 females, with a mean age of 23.63±4.10 years) received INB intraoperatively and IPCA postoperatively, and a postoperative intravenous patient-controlled analgesia (IPCA) group, in which 38 patients (33 males, 5 females, with a mean age of 24.93±6.34 years) only received IPCA postoperatively. Their general clinical data and the postoperative pain visual analogue scale (VAS) were recorded. Analgesia-associated side effects, rate of the pulmonary infection were observed. Expenses associated with analgesia during hospital were calculated. Results The score of VAS, the incidence of nausea and vomiting, fatigue and other side effects, pulmonary atelectasis and the infection rate in the INB+IPCA group were significantly lower than those in the IPCA group. Postoperative use of analgesic drugs was significantly less than that in the IPCA group. Medical expenses did not significantly increase. Conclusion INB+IPCA is beneficial for fast track surgery after thoracoscopic resection of lung bullae.
Objective To investigate the status quo of implementation ofIntravenous Practice Standard in a tertiary A hospital in Sichuan. Methods At 09:00-11:30 am, on March 16th, 2016, a questionnaire designed by intravenous team (IV Team) was used to conduct the investigation in all the inpatiets according to inclusion and exclusion criteria. The SPSS 17.0 software was used to perform all statistical analysis. Results The intravenous infusion rate in the hospital was 76.87%, while the rate in Emergency Department peaked up to 96.11%. Indwelling needle was the most common used device for intravenous therapy in clinical practice, which was used in 77.91% of the inpatients, and steel needle, peripherally inserted central catheter (PICC), central venous catheter, and implantable venous access port were also widely used. Peripheral intravenous catheter was used in 2 990 inpatients, and 78.12% of the puncture sites met the standard; PICC was used in 397 inpatients, and 90.17% of the puncture sites met the standard. The incidence of intravenous infusion related-complications was 15.08%, the incidence of drug exosmosis / exudation was 10.06%, and the incidence of catheter-related blood stream infection (CRBSI) was 2.89%. Conclusions On the whole, the intravenous infusion rate in this hospital accords with the national average level, but the rate in some departments should be controlled. The selection of device for intravenous therapy is reasonable, but the selection of intravenous site should be more standardized. The incidence of intravenous infusion related-complications is low, but the prevention and control of drug exosmosis / exudation and CRBSI should be reinforced. Health care organizations should pay more attention to enforce the Intravenous Practice Standard into practice to promote clinical medical service.
Objective To assess the effectiveness of intravenous immunoglobulin G (IVIG) in reducing the need for exchange transfusion in neonates with proven haemolytic disease due to Rh and/or ABO incompatibility. To evaluate the effectiveness of IVIG in reducing the duration of phototherapy and hospital stay. Methods We electronically searched CENTRAL, MEDLINE (1966 to May 2008), EMBASE (1992 to May 2008), CBMdisc (November 1979 to May 2008), and also checked the reference lists of all papers identified. According to the Cochrane Handbook for Systematic Reviews of interventions, randomized controlled trials comparing IVIG and phototherapy with phototherapy alone in neonates with Rh and/or ABO incompatibility were identified and analyzed. Results Six RCTs were included. The meta-analysis showed that, IVIG can significantly decrease the requirements of exchange transfusion (RR=0.27, 95%CI 0.18 to 0.42), the duration of hospitalization (WMD= –1.11, 95%CI –1.60 to –0.63) and the duration of phototherapy (WMD= –0.82, 95%CI –1.16 to –0.47). Conclusions Intravenous immunoglobulin (IVIG) is recommended for treating hemolytic disease of the newborn because it is effective in decreasing the requirements of exchange transfusion, the duration of hospitalization and phototherapy. Well designed studies with large sample in multi-center are required for further proving.
ObjectiveTo compare postoperative patient-controlled epidural analgesia (PCEA) and intravenous patient-controlled analgesia (PCIA) on maternal low back pain after caesarean section. MethodsSixty cases of American Society of Anesthesiology gradeⅠ-Ⅱ single-birth full-term elective caesarean delivery primiparae chosen between July to September 2012 were divided into 3 groups randomly, 20 in each group. Group A accepted sufentanil 1 μg/mL and ropivacaine 1 mg/mL PCEA; group B had sufentanil 1.5 μg/mL PCEA; group C was given sufentanil 1.5 μg/mL and ondansetron 0.16 mg/mL PCIA. Background dose was 2 mL/h, patient-controlled analgesia dose was 2 mL, and locking time was 20 min. Visual analogue pain score was used to assess the effect of postoperative analgesia, and we recorded analgesia pump usage, adverse reactions, and at the same time investigated the onset of maternal low back pain. ResultsNo obvious postoperative pain was found, and the analgesic effect was good in all the three groups, and the differences were not statistically significant (P>0.05). All three groups of women had a certain proportion of low back pain, and the differences were not statistically significant (P>0.05). After operation, group A had 5 cases of leg numbness, group B had 1, and group C had none. Leg numbness occurred significantly more in group A than in group B and C (P<0.05). Group B had one case of nausea and vomiting, while none occurred in group A and C (P>0.05). ConclusionWith the same effect of postoperative analgesia, compared with PCIA, PCEA does not increase postoperative low back pain incidence after caesarean section.
