OTTAWA: What scientists here have discovered is rare! Patients who have surgical treatments at nighttime are twofold more liable to pass away as compared to patients who were operated on the daylight hours!!

The researchers have attempted to look into the association among postoperative death and the time of the day (daytime, evening, night) of operation.

For conducting the study, investigators here have analyzed all surgical measures for almost five-year along with a retrospective assessment of 30 days postoperative death at the hospital.

As per the estimates, some 41,716 elective and urgent situation surgeries carried out on 33,942 patients in 40,044 hospitals.

Associate Professor from the McGill University Health Centre, Michael Tessler lamented: “This study demonstrates that late day and night emergency surgeries are associated with higher mortality when factoring in American Society of Anesthesiologists (ASA) score and patient age.”

Tessler further held: “Postoperative 30-day in-hospital mortality rate should include start time of anaesthesia, along with other known variables, as a risk factor.”

Their findings suggested that people who were operated-on at hours of darkness have been reported 2.17 times and patients who have surgery in the afternoon were 1.43 times more prone to die in comparison to those who have surgeries during daytime.

The study has been published in the journal World Federation of Societies of Anaesthesiologists.
