The Relationship Between Sleep Quality Before Surgery and Severity of Headache after Spinal Anesthesia in Cesarean Section in Imam Sajjad Hospital, Yasuj

Sleep disturbance is one of the major complaints of patients referring to clinical clinics. Empirical and cross-sectional studies have shown a two-way relationship between pain and sleep, in which an inappropriate sleep can lead to pain relief and pain can interfere with the quality and continuation of sleep. The aim of this study was to determine the relationship between the quality of sleep before surgery and the severity of headache after spinal anesthesia. This cross-sectional study was descriptive-analytic. In this study, 90 pregnant women who were candidates for voluntary cesarean section with spinal anesthesia were selected randomly after receiving written and informed consent. Sleep quality one month before delivery was measured by Pittsburgh sleep inventory questionnaire and the spinal anesthesia severity score was assessed in 48 hours after spinal anesthesia and seven days later by numerical pain scale. Data were analyzed using descriptive statistics, Spearman correlation coefficient, mean and standard deviation. The mean and standard deviation of 90 subjects in the study was 29.8±5.56. The mean and standard deviation of sleep quality score were 13.13±2.1. In 48 hours after spinal anesthesia, 24(26.7%) of the participants reported a degree of headache. On the 7th day after spinal anesthesia, 27(30%) participants reported a degree of headache. A significant relationship was seen between sleep quality score and severity of headache during 48 hours after spinal anesthesia (p=0/039). No significant relationship was observed between sleep quality score and severity of headache in 7 days after spinal anesthesia (p=0/59). There was a significant correlation between severity of headache 48 hours after spinal anesthesia and severity of headache 7 days later (p=0/0001). There was no significant relationship between sleep quality score and age. There was no significant relationship between age and severity of headache 48 hours after anesthesia. The relationship between sleep quality and spinal headache has been shown to be due to the role of sleep and its disorders on neurotransmitter sleep systems and indirect effects on dopaminergic and opioidergic, serotonergic and melatonin systems.
