ABSTRACT
Objective To investigate the impact of sputum suction under laryngoscope in stroke patients on the occurrence and prognosis of ischemic stroke-associated pneumonia (SAP).Methods A total of 127 cases with acute ischemic stroke (AIS) with Glasgow Coma Scale 6-12 scores,non-artificial airway and need for intensive care were enrolled.According to the suction practice,the cases were divided into laryngoscope euthyphoria group (practice group,PG,n =59),and conventional oral or nasal sputum suction group (control group,CG,n =68).The PG was perspectively studied,while the CG were analyzed retrospectively.All patients were cared with the Guidelines for the management of adult with hospitalacquired ventilator-associated and healthcare-associated pneumonia set by American Thoracic Society/Infectious Diseases Society of America in 2005 and the Guidelines for the early management of patients with acute ischemic stroke set by American Heart Association/American Stroke Association in 2013 including patting on the back of patients in prone position routinely in order to facilitating expectoration,phlegm elimination with physical vibration and apophlegmatic agent application during their stay in ICU.Incidences of SAP and 28-day mortality were calculated.Levels of inflammatory markers (white blood cell,WBC;highsensitive C-reaction protein;procalcitonin,PCT) in serum were detected.Adverse events related to laryngoscopy were documented.Results There were no significant differences in incidences of SAP and 28-day mortality between PG and CG groups (32.20% vs.41.18%,P > 0.05;47.37% vs.53.57,P > 0.05,respectively).However,there was statistically significant difference (P < 0.05) in the ICU stay length and inflammatory markers,and the sputum suction process in PG did decrease the incidence of artificial airway establishment and mechanical ventilation (18.64% vs.35.29%,P < 0.05),and the laryngoscope euthyphoria method was proved to be a protective factor (HR =0.515;95% CI 0.281-0.057,P =0.038).WBC and PCT were lower in PG group than in CG group (P < 0.05).Conclusion Sputum suction under laryngoscope can reduce the probability of artificial airway establishment and invasive ventilator employment in patients with AIS,shortening ICU stay length and down-regulating levels of WBC and PCT.
