|
| Secondary |
Leakage |
presence of any leakage from catheter fixation |
immediately after surgery in PACU and daily until the patient is discharged up to post-operative day 7 |
|
| Secondary |

immediately after surgery in PACU and daily until the patient is discharged up to post-operative day 7 |
|
| Secondary |
Opioid consumption |
Daily oral morphine equivalent totals |
daily up to 7 days post-operative |
