Anaesthesia induction time was 10 (+/- 3) minutes in the GA group, 10 (+/- 5) minutes in the IVRA group and 28 (+/- 17) minutes in the BOB group. There were statistically significant differences between IVRA and BPB and between BPB and GA.
Anaesthesia surgery time was 59 (+/- 33) minutes in the GA group, 45 (+/- 26) minutes in the IVRA group and 53 (+/- 21) minutes in the BPB group. The difference was not statistically significant.
Total anaesthesia time was 83 (+/- 29) minutes in the GA group, 72 (+/- 30) minutes in the IVRA group and 106 (+/- 27) minutes in the BPB group. There were statistically significant differences between IVRA and BPB and between BPB and GA, (p<0.005).
PACU recovery time was 70 (+/- 14) minutes with GA, 45 (+/- 21) minutes with IVRA and 63 (+/- 32) minutes with BPB. There were statistically significant differences between IVRA and BPB and between IVRA and GA, (p<0.005).
DSU recovery time was 86 (+/- 55) minutes with GA, 63 (+/- 34) minutes with IVRA and 77 (+/- 50) minutes with BPB. The difference between IVRA and GA was statistically significant, (p<0.005).
Total hospital time was 240 (+/- 75) minutes in the GA group, 180 (+/- 58) minutes in the IVRA group and 244 (+/- 68) minutes in the BPB group. There were statistically significant differences between IVRA and BPB and between IVRA and GA, (p<0.005).
The proportion of patients experiencing pain requiring opioid analgesics was 85% with GA, 51% with IVRA and 43% with BPB. There were statistically significant differences between GA and the other two techniques, (p<0.005).
The incidence of nausea and vomiting requiring antiemetic medication was 62% with GA, 18% with IVRA and 12% with BPB. There were statistically significant differences between GA and the other two techniques, (p<0.005). However, the authors reported that 2 patients in the IVRA group and 3 in the BPB group required GA due to failure of the anaesthetic block.
