If you are going for a surgery then u must ask your doctor to perform it in the day-time, as a new study by the researchers of McGill University Health Centre, in Montreal, Canada found that the possibility of death in a surgery is doubled when it is performed at night or evening time as compared to the ones taking place in the day time.
The objective of the research was to obtain the relationship between deaths during surgeries and the time during which it is performed, so that it may help people to choose a right time to decrease the risk of surgery failure.
Data from Jewish General Hospital in Montreal was analysed for last 5 years of the surgeries from April 1st 2010 to 31st March 2015 and an extra 30 days of time was used to examine the surgeries in the hospitals, 41,716 surgeries both planned and emergency, were observed during the period. The time was divided as- 7am-3:29pm: Daytime, 3:30pm-11:29pm: Evening time and 11:30pm-7:29am as Night time.
The results were such that the surgeries taking place in the night time had 2.17 times more risk of death as compared to day time surgeries, and the ones occurring in the evening had 1.43 times more death rates than morning surgeries.
The reason of this could be the lack of staff at the nigh time, provider fatigue during anaesthesia and surgery, lack of operation theatres in the emergency cases, delay in the treatment of a person who is too weak or sick. All these factors can be analysed more carefully so that the mortality rates may fall.
Researchers said “Postoperative 30-day in-hospital mortality rate should include start time of anaesthesia, along with other known variables, as a risk factor”.
The research was presented in ‘World Congress of Anaesthesiologists’, which is being held in Hong Kong from starting from August 28 to September 2.
