Objectives To assess the effectiveness and safety of lumbar continuous drainage of the cerebrospinal fluid therapy for subarachnoid hemorrhage (SAH). Methods The method of Cochrane systematic review was used to evaluate the randomized controlled trials (RCTs) of lumbar contiunous drainage of the cerebrospinal fluid therapy for SAH. Results We included 7 RCTs involving 390 patients. The methodological quality of all the trials was poor. The poor outcome and adverse event evaluation of the SAH patients at the end of long-term follow-up (at least three months) were not reported in all studies. Meta-analysis of fatality showed a better effect of lumbar continuous drainage of the cerebrospinal fluid therapy for SAH than the control group with statistical significance [RR=0.32, 95%CI (0.15, 0.70)]. Meta-analysis of complications also showed a better effect of lumbar continuous drainage of the cerebrospinal fluid therapy for SAH than the control group with statistical significance (except re-bleeding) [cerebral vasospasm RR=0.15, 95%CI (0.06, 0.33), hydrocephalus RR=0.22, 95%CI (0.10, 0.52), cerebral infarction RR=0.25, 95%CI (0.08, 0.82)]. Only one trial reported the adverse events of lumbar continuous drainage of the cerebrospinal fluid therapy including intracranial infection and intracranial hypotension reaction, while the other trials did not report the adverse events. Conclusion With poor quality of the most included trials, insufficient evidence is obtained to support the conclusion that lumbar continuous drainage of the cerebrospinal fluid therapy is safe and effective in the treatment of SAH. Further high-quality RCTs should be carried out to provide more reliable evidence.
ObjectiveTo assess the effectiveness and safety of continuous lumbar drainage of cerebrospinal fluid for subarachnoid hemorrhage (SAH). MethodsThe Cochrane Library (January 1992 to May 2013), Medline (January 1950 to May 2013), SinoMed (January 1979 to May 2013), CNKI (January 1979 to May 2013), and Wanfang Database (January 1979 to May 2013) were searched for randomized controlled trials (RCTs) on continuous lumbar drainage for SAH. The method of Cochrane systematic review was used to evaluate all the included RCTs. ResultsTwelve RCTs (857 patients) met the inclusion criteria, but the general methodological quality of trials was poor. Only two studies addressed the outcomes about SAH patients' death, vegetative state or disability and other adverse events at the end of the follow-up period (at least 3 months). Meta-analysis of fatality showed a better effect of lumbar continuous drainage of the cerebrospinal fluid for SAH than the control group with statistical significance [RR=0.27, 95%CI (0.12, 0.59), P=0.001]. Meta-analysis of complications also showed a better effect of lumbar continuous drainage of the cerebrospinal fluid for SAH than the control group with statistical significance (except re-bleeding) [cerebral vasospasm: RR=0.20, 95%CI (0.14, 0.30), P<0.000 01; hydrocephalus: RR=0.24, 95%CI (0.13, 0.41), P<0.000 01; cerebral infarction: RR=0.27, 95%CI (0.16, 0.45), P<0.000 01]. Only one trial reported the adverse events of lumbar continuous drainage of the cerebrospinal fluid including intracranial infection and intracranial hypotension reaction, while the others did not report the adverse events. ConclusionWith poor quality of the most included trials, insufficient evidence is obtained to support the conclusion that lumbar continuous drainage of the cerebrospinal fluid is safe and effective in the treatment of SAH. Further high-quality RCTs should be carried out to provide more reliable evidences.
Objective To observe and evaluate the efficacy of continuous drainage with intravenous catheter in the treatment of breast abscess infected by methicillin resistant staphylococcus aureus (MRSA) and to explore the best treatment methods. Methods Sixty cases of breast abscess infected by MRSA were retrospectively analyzed. The patients were divided into continuous drainage group and puncture drainage group according to the treatment. Continuous drainage with 14G intravenous catheter and intermittent aspiration with 20 mL syringe were performed to treat the breast abscesses in the continuous drainage group (n=36) and puncture drainage group (n=24), respectively. Meanwhile, sensitive antibiotics were used according to the results of susceptibility test. The therapeutic effects of the 2 groups were compared. Results There were no significant differences in baseline data between continuous drainage group and puncture drainage group (P>0.05). There was no significant differences of cure rate between the two groups (P=0.717). Compared with the puncture drainage group, the continuous drainage group showed shorter period of time to heal the breast abscess (P=0.001), shorter period of time to control the ache (P=0.038), less punctures (P<0.001) and more daily volume of drainage (P<0.001). No significant differences were found in the period of time to control the fever between the two groups (P=0.127). Conclusions Continuous drainage with intravenous catheter can shorten the course of disease, reduce the suffering of patients, reduce the difficulty of hospital infection prevention and control. It’s an ideal choice for the treatment of breast abscess infected by MRSA.
