Selected AbstractsEffectiveness of cutaneous warming systems on temperature control: meta-analysisJOURNAL OF ADVANCED NURSING, Issue 6 2010Cristina Maria Galvão galvão c.m., liang y. & clark a.m. (2010) Effectiveness of cutaneous warming systems on temperature control: meta-analysis. Journal of Advanced Nursing,66(6), 1196,1206. Abstract Title.,Effectiveness of cutaneous warming systems on temperature control: meta-analysis. Aim., This paper is a report of a meta-analysis to identify the effectiveness of different types of cutaneous warming systems in temperature control for patients undergoing elective surgery. Background., Hypothermia is a common and serious complication of surgery. Different cutaneous warming systems are used to prevent hypothermia during surgery but there have been no previous meta-analyses of the effectiveness of different warming systems in controlling temperature. Data sources., We conducted a search of the CINAHL (2000 to April 2009), Medline (2000 to April 2009), Embase (2000 to April 2009) and the Cochrane Register of Controlled Trials (2000 to April 2009) databases for randomized controlled trials published in English, Spanish and Portuguese. The primary outcome measure of interest was core body temperature. Methods., A systematic review incorporating meta-analysis was carried out. Results., From 329 papers, 23 trials compared warming systems. Forced-air warming systems had a strong tendency towards superior temperature control over passive insulation via cotton blankets (mean difference: 0·29°C; 95% confidence interval: ,0·02 to 0·59, three trials 292 patients) and radiant warming systems (mean difference: 0·16°C; 95% confidence interval: ,0·01 to 0·33, three trials, 161 patients). However, circulating water garments tended to be more effective than forced-air warming systems (mean difference: ,0·73°C; 95% confidence interval: ,1·51 to 0·05, I2 = 97%; four trials, 198 patients). Pooled results approached statistical significance and indicated clinically meaningful differences in temperature control. Conclusion., Current evidence suggests that circulating water garments offer better temperature control than forced-air warming systems, and both are more effective than passive warming devices. [source] A systematic review of the effectiveness of cutaneous warming systems to prevent hypothermiaJOURNAL OF CLINICAL NURSING, Issue 5 2009Cristina M Galvão Aims., To retrieve and critique recent randomised trials of cutaneous warming systems used to prevent hypothermia in surgical patients during the intraoperative period and to identify gaps in current evidence and make recommendations for future trials. Background., Hypothermia affects up to 70% of anaesthetised surgical patients and is associated with several significant negative health outcomes. Design., Systematic review using integrative methods. Methods., We searched CINAHL, EMBASE, Cochrane Register of Controlled Trials and Medline databases (January 2000,April 2007) for recent reports on randomised controlled trials of cutaneous warming systems used with elective patients during the intraoperative period. Inclusion criteria., We included randomised control trials examining the effects of cutaneous warming systems used intraoperatively on patients aged 18 years or older undergoing non-emergency surgery. Studies published in English, Spanish or Portuguese with a comparison group that consisted of either usual care or active cutaneous warming systems without prewarming were reviewed. Results., Of 193 papers initially identified, 14 studies met the inclusion criteria. There was moderate evidence to indicate that carbon-fibre blankets and forced-air warming systems are equally effective and that circulating-water garments are most effective for maintaining normothermia during the intraoperative period. Few trials reported costs. Conclusions., Carbon-fibre blankets and forced-air warming systems are effective and circulating-water garments may be preferable. Future research should measure the direct and indirect costs associated with competing systems. Relevance to clinical practice., Nurses can use this review to inform their selection of warming interventions in perioperative nursing practice. They can also assess other factors such as nursing workload, staff training and equipment maintenance, which should be incorporated into future research. [source] | ||||||||||
