ABSTRACT

Introduction Surgical stress response can cause sleep disturbance in the postoperative period. Our study aims to assess the prevalence of insomnia and to find out the factors causing it in the perioperative period in patients undergoing cancer surgery in a tertiary cancer center in India. Aim To find out the prevalence of insomnia in the perioperative period in patients undergoing cancer surgeries Methods The insomnia severity index was used to assess the presence of insomnia preoperatively, 48 hours after surgery, and two weeks after surgery. Possible factors influencing insomnia are classified as personal (Age, gender, substance abuse, educational status, marital status, comorbidities), surgery and anesthesia related (Type of surgery, site of surgery, type of anesthesia, level of pain, analgesia used) and its influence on postoperative insomnia was assessed. Results Insomnia is present in 28% of patients in the preoperative period, 54% in the immediate postoperative period, and 35% of patients two weeks after surgery. Age, educational status, tobacco chewing, marital status, and presence of comorbidities have a significant influence on the occurrence of insomnia. Type of surgery, type of anesthesia, level of pain, and type of analgesia used significantly influence postoperative insomnia. Conclusion Insomnia is a major problem in the perioperative period which is often unnoticed. Proper counseling must be given to patients if needed to facilitate a faster postoperative recovery and also to reduce the financial burden of prolonged hospital stay.
