Table 4.
Spearman’s rho rank correlation coefficient (Rho) between total mg of ropivacaine administered epidurally and OCTT
| Ropivacaine (mg) | OCTT1 | OCTT3 |
|---|---|---|
| Intraoperatively | Rho = −0.49 p = 0.005 |
Rho = −0.31 p = 0.093 |
| 1st postoperative day | Rho = −0.32 p = 0.083 |
Rho = −0.4 p = 0.03 |
| 3rd postoperative day | Rho = −0.29 p = 0.12 |
Rho = −0.43 p = 0.02 |
Values close to +1 or −1 indicate strong association between variables. p values <0.05 represent statistically significant results. OCTT 1 oro-ceacal transit time the first postoperative day, OCTT 3 oro-ceacal transit time the third postoperative day
