Background:
Lumbar continuous drainage of fluid (LCDF) has become more widely used in the diagnosis and treatment of neurological diseases in recent years. The use of LCDF can enable a better understanding of the patient's condition and reduce the incidence of related complications. LCDF can also affect complications of perforation surgery, including mortality during hospitalization, cerebral vasospasm (CVS), bleeding, and aneurysmal subarachnoid hemorrhage (aSAH).
Methods:
Articles published from library construction to April 2021 were searched for in the English-language databases PubMed, Cochrane Library, and Embase. All randomized controlled trials (RCTs) with LCDF and hole locking surgery were meta-analyzed using the Cochrane Collaboration's RevMan 5.3 software.
Results:
Ten RCTs involving 1,092 patients (continuous drainage group, n=585; control group, n=507) were included in the meta-analysis. For the statistical different in incidence of perioperative cerebral infarction in the two groups, the odds ratio (OR) was 5.42 [95% confidence interval (CI): (2.71, 10.83); P<0.00001], and for the statistical difference in the incidence of cerebral hemorrhage, the OR was 4.76 [95% CI: (2.11, 10.76); P=0.0002]. Perioperative complications were fewer in the LCDF-treated drainage group than in the conventional group.
Discussion:
This meta-analysis of 10 RCTs confirmed that LCDF compared with other treatments is associated with a lower incidence of perioperative complications, such as cerebral hemorrhage, hydrocephalus, and cerebral infarction, as well as increased Glasgow Outcome Scale (GOS).
