[The efficacy of hypertonic saline treatment in cardiopulmonary resuscitation in animal model with cardiac arrest: a Meta-analysis].
Zhonghua Wei Zhong Bing Ji Jiu Yi Xue 2015 March
OBJECTIVE: To evaluate the efficacy of hypertonic saline (HS) treatment in cardiopulmonary resuscitation (CPR) in animal models of cardiac arrest (CA).
METHODS: PubMed and EMBASE data were retrieved from January 1st, 1966 to September 30th, 2014, and Wanfang data and CNKI were searched from January 1st, 1990 to September 30th, 2014 for randomized controlled trials (RCTs) regarding CPR intervention of CA animal models with HS. HS was intravenously infused at the initiation of CPR in HS group, without limiting its dosage or concentration. The same volume of normal saline (NS) was given in NS group. Meta-analysis concerning the rate of restoration of spontaneous circulation (ROSC), the serum sodium concentration before CA and during CPR, and related hemodynamic parameters, including mean arterial pressure (MAP) and coronary perfusion pressure (CPP) at the immediate beginning of CPR and 90 minutes after ROSC was conducted by RevMan 5.3 software.
RESULTS: A total of 8 RCTs were included. Meta-analysis showed that compared with NS group, the rate of ROSC [relative risk (RR) = 1.23, 95% confidence interval (95%CI) = 1.05-1.43, P = 0.010], serum sodium concentration during CPR [weight mean difference (WMD) = 17.44, 95%CI = 12.57-22.31, P < 0.01], and the level of MAP at 90 minutes after ROSC (WMD = 4.81, 95%CI = 1.58-8.03, P = 0.003) were significantly improved in HS group. There was no significant statistic difference in other hemodynamic parameters, including serum sodium concentration before CA (WMD = 0.78, 95%CI = -0.26-1.82, P = 0.14), MAP (WMD = 5.43, 95%CI = -0.74-11.59, P = 0.08) and CPP at the immediate beginning of CPR (WMD = 6.82, 95%CI = -5.54-19.19, P = 0.28), and CPP at 90 minutes after ROSC (WMD = -0.77, 95%CI = -10.33-8.80, P = 0.88) between two groups. It was showed by funnel chart that bias was not significant in the published articles.
CONCLUSIONS: This systematic review indicates that HS infusion is followed by an improved ROSC rate, serum sodium concentration during CPR, and MAP at 90 minutes after ROSC in animal models of CA.
