BACKGROUND AND OBJECTIVES
Oxygen is routinely supplemented in patients of regional anaesthesia. There are many pros and cons in the use of oxygen supplementation and its real benefit. In our study we tried to find out the effect of oxygen supplementation on the haemodynamic parameters, oxygen saturation, post-operative nausea vomiting and wound healing.
MATERIAL AND METHODS
The study was a prospective randomized controlled trial. Two hundred and forty patients belonging to ASA 1 physical status of either gender, aged 30-65 years were randomly allocated into two equal groups; group O and group N. Group O: Control group in which oxygen was supplemented through Ventimask Group N: Study group in which oxygen was not supplemented. They underwent elective lower abdominal surgery including general surgery, orthopaedics and gynaecological surgeries. Both the groups were compared for haemodynamic parameters, oxygen saturation (SpO2), post-operative nausea vomiting and surgical site infection.
RESULTS
The mean pulse rate (intra operative) in group O was 83.45±11.82/min. In group N it was 84.01±11.88. The mean systolic blood pressure (intraoperative) in group O was 107.83±13.37/mmHg. In group N it was 106.62±11.03 mmHg. The mean diastolic blood pressure in group O was 72.56±0.51 mmHg and in group N it was 70.75±7.53 mmHg. The mean oxygen saturation in group N was 97.4%±1.09 while in group O it was 99.3%±1.15. There was no statistical significant difference in both the groups for haemodynamic parameters and oxygen saturation (P >0.05). 16 patient had post-operative nausea vomiting in group N while 15 patients in group O. There was no statistical significant difference between the two groups for post-operative nausea vomiting (P>0.05). 12 patients had surgical site infection in group N while the number was 10 in group O. There was on statistical significant difference between the two groups for surgical site infection. (P value was >0.05)
CONCLUSION
There was no statistically significant difference for pulse rate, blood pressure, post-operative nausea vomiting and surgical site infection in between the two groups i.e. with and without oxygen supplementation groups.
