Abstract：Objective To explore the effect of sputum aspiration depth on airway secretion clearance and blood pressure among patients with hypertensive intracerebral hemorrhage.Methods Totally 108 patients with hypertensive intracerebral hemorrhage and treated in auother's hospital between March 2020 and April 2023 were selected,and divided into a control group and an observation group,each of 54,according to a random number table.The control group underwent conventional superficial sputum aspiration after surgery,while the observation group underwent deep sputum aspiration.The blood oxygen saturation,brain tissue oxygen saturation,sputum sound and blood pressure were compared between the two groups before and after sputum aspiration.Results There were no significant differences between the 2 groups in the blood oxygen saturation and brain tissue oxygen saturation in the time effect,intergroup effect and interaction effect(all P＞0.05).The improvement of sputum singing in the observation group was significantly greater than that of the control group(t=6.301,P＜0.001).Moreover,after sputum aspiration,the systolic blood pressure and diastolic blood pressure of the observation group were significantly higher than that of the control group(t=2.101,P=0.038;t=2.159,P=0.033).Conclusion Deep sputum aspiration is more conducive to the removal of airway secretions,while shallow sputum aspiration helps to keep the blood pressure at a stable level.
