Objective:To observe the effect of individualized nursing on obesity patients with obstructive sleep apnea hypopnea syndrome(OSAHS)after bariatric surgery and its effect on sleep quality.Methods:Seventy obese patients with OSAHS admitted to the Department of General Surgery of the First Affiliated Hospital of Xiamen University were selected as the study objects,and were divided into observation group and control group by random number table method,with 35 cases in each group.The control group was treated with routine nursing methods,and the observation group was treated with individualized nursing on the basis of the control group.Sleep related indexes[apnea frequency,hypopnea index and Pittsburgh Sleep Quality Index(PSQI)score],sleepiness degree[Epworth Sleepiness Scale(ESS)score]and nasal congestion degree[visual analog scale(VAS)score]were compared before and after care of patients in 2 groups,and nursing satisfaction of patients in 2 groups was investigated.Results:After nursing,the frequency of apnea,hypopnea index and PSQI score in 2 groups were lower than those before nursing(P<0.05),and the frequency of apnea,hypopnea index and PSQI score in observation group were significantly lower than those in control group(P<0.05).After care,ESS score and nasal obstruction VAS score in 2 groups were lower than those before care(P<0.05),and ESS score and nasal obstruction VAS score in observation group were significantly lower than those in control group(P<0.05).The total nursing satisfaction of the observation group was 94.29%(33/35),and that of the control group was 77.14%(27/35).The total nursing satisfaction of the observation group was higher than that of the control group(P<0.05).Conclusion:Individualized nursing for obese patients with obstructive OSAHS after bariatric surgery can effectively improve their sleep quality,reduce drowsiness and nasal congestion,and improve patient satisfaction.
