Effect of angioembolisation versus surgical packing on mortality in traumatic pelvic haemorrhage: A systematic review and meta-analysis

引用

World Journal of Emergency Medicine 2018年第2期9卷 85-92页

作者： Ahmed El Muntasar ethan Toner Oddai A.Alkhazaaleh Danaradja Arumugam Nikhil Shah Shahab Hajibandeh Shahin Hajibandeh Department of General Surgery Royal Blackburn Hospital Department of Trauma and Orthopaedics WrightingtonWigan and Leigh NHS Foundation Trust Department of General Surgery Salford Royal Hospital Department of General Surgery North Manchester General Hospital

BACKGROUND: The management of complex pattern of bleeding associated with pelvic trauma remains a big challenge for trauma surgeons. We aimed to conduct a comprehensive meta-analysis to compare the outcomes of angioembolisation and pelvic packing in patients with pelvic ***: We conducted a systematic search of electronic information sources, including MEDLINE; EMBASE; CINAHL; the CENTRAL; the World Health Organization International Clinical Trials Registry; Clinical ***; ISRCTN Register, and bibliographic reference lists. The primary outcome was defined as mortality. Combined overall effect sizes were calculated using randomeffects models. Results are reported as the odds ratio(OR) and 95% confidence interval(CI).RESULTS: We identified 3 observational studies reporting a total of 120 patients undergoing angioembolisation(n=60) or pelvic packing(n=60) for pelvic trauma. Reporting of the Injury Severity Score(ISS) was variable, with higher ISS in the pelvic packing group. The risk of bias was low in two studies, and moderate in one. The pooled analysis demonstrated that angioembolisation did not significantly reduce mortality in patients with pelvic trauma compared to surgery(OR=1.99; 95% CI= 0.83–4.78, P=0.12). There was mild between-study heterogeneity(I^2=0%, P=0.65).CONCLUSION: Our analysis found no significant difference in mortality between angioembolisation and pelvic packing in patients with traumatic pelvic haemorrhage. The current level of evidence in this context is very limited and insufficient to support the superiority of a treatment modality. Future research is required.

Purpose:The purposes of the present study were:(1)to determine whether the physical working capacity at the fatigue threshold(PWCFT)model that has been used for estimating the onset of neuromuscular fatigue in the vastus lateralis(VL)during incremental treadmill running could also be applied to the vastus medialis(VM),biceps femoris(BF),and semitendinosus(ST)muscles;and(2)if applicable,to compare the running velocities associated with the PWCFT among these ***:Eleven subjects(age 21.7±1.8 years)performed an incremental treadmill test to exhaustion with electromyographic signals recorded from the VL,VM,BF,and ***:The results indicated there were no significant(p>0.05)mean differences in the running velocities associated with the PWCFT for the VL(14.4±2.0 km/h),VM(14.3±1.9 km/h),BF(13.8±1.8 km/h),and ST(14.7±2.3 km/h).In addition,there were significant inter-correlations(r=0.68-0.88)among running velocities associated with the PWCFT of each *** results also indicated that 9 of the 11 subjects exhibited identical PWCFT values for at least 3 of the 4 muscles,but there were no uniform patterns for any intra-individual ***:The findings of the present study suggested that the PWCFT test is a viable method to identify neuromuscular fatigue in the quadriceps and hamstrings during incremental treadmill exercise and results in consistent PWCFT values among these muscles.
