Comparative Study of Continuous Versus Intermittent Subglottic Suction Drainage to Prevent Ventilator Associated Pneumonia in Intubated Patients (original) (raw)
2021, Birat Journal of Health Sciences
Introduc on Subglo c secre on drainage reduces the incidence of ven lator associated pneumonia (VAP). The efficacy of Con nuous subglo c secre on drainage (CSSD) over Intermi ent subglo c secre on drainage (ISSD) for preven on of VAP is unknown. Objec ves Compare the efficacy of CSSD and ISSD in terms of incidence of VAP, mortality, dura on of mechanical ven la on, length of ICU stay and incidence of reintuba on. Methodology This was a prospec ve compara ve study conducted at Birat Medical College and Teaching Hospital. A total number of 80 intubated pa ents for at least 48 hours dura on were included. Con nuous and intermi ent endotracheal suc oning techniques were compared for preven on of VAP and secondary outcomes in terms of length of mechanical ven la on, length of ICU stay, mul organ failure, reintuba on and mortality rate. Result The incidence of VAP was 15% and 22.5 % in CSSD group while it was 17.5% and 27.5% in ISSD group in first 48 hours and 96 hours of mechanical ven la on respec vely.The length of mechanical ven la on was significantly less in con nuous group (4.78 ± 2.50 days) than in intermi ent group (7.18 ± 2.09 days) with p value of 0.023. The pa ents with CSSD had significantly shorter ICU stay (5.49 ± 3.16 days) as compared to the pa ents with ISSD (8.46 ± 2.06 days). The incidence of reintuba on was significantly higher in intermi ent group pa ents (p value 0.024). Pa ents in both the group had comparable incidence of mul organ failure, spontaneous breathing trial and mortality rate. Conclusion The incidences of VAP and mortality were comparable in CSSD and ISSD. However CSSD significantly decreased the dura on of mechanical ven la on, length of ICU stay and incidence of reintuba on..
