Brief summary

the purpose of this study is to compare opioid consumption in morphine equivalents between the groups that received postoperative analgesia with intrathecal morphine versus US guided QL blocks versus US guided QL catheters

Interventions

DRUGIntrathecal morphine sulfate (ITM)

Spinal anesthesia with ITM + US guided QLB single shot sham block + QLB catheters with no continuous infusion

DRUGBupivacaine hydrochloride

Spinal anesthesia without ITM + US guided QLB single shot with bupivacaine hydrochloride + QLB catheters with no continuous infusion

Spinal anesthesia without ITM + US guided QLB single shot with bupivacaine hydrochloride + QLB catheters continuously infusing 0.2% ropivacaine hydrochloride

MeasureTime frameDescription
Static Pain as Measured by the Numerical Pain Score (NPS)6, 12, 24, 48 and 72 hours post surgeryTo assess static pain scores, NPS will be recorded while the participant is supine in bed. NPS is a 11-point scale with a higher number indicating more severe pain (total score ranges from 0 to 10).
Severity of Pruritus as Assessed by a Scale24, 48 and 72 hours post surgeryThis numeric scale is a 11-point scale with a higher number indicating an extremely severe side effect. Total score ranges from 0 to 10.
Severity of Nausea as Assessed by a Scale24, 48 and 72 hours post surgeryThis numeric scale is a 11-point scale with a higher number indicating an extremely severe side effect. Total score ranges from 0 to 10.
Severity of Vomiting as Assessed by a Scale24, 48 and 72 hours post surgeryThis numeric scale is a 11-point scale with a higher number indicating an extremely severe side effect. Total score ranges from 0 to 10.
Total Narcotic Consumption in Morphine Equivalents (in Milligrams)12,24,48 hours post surgeryTotal narcotic consumption in morphine equivalents (in milligrams) for 12, 24 and 48 hours after surgery was calculated.
Patient Satisfaction as Assessed by Likert Scale24 hours post surgeryPatient reported a score for each of 4 different aspects of satisfaction: their quality of sleep, ability to ambulate, ability to breast or formula feed, and ability to feed and take care of newborn. Each of the 4 aspects of satisfaction were rated on a 5-point Likert scale as follows: Extremely satisfied (5), Very satisfied (4), Moderately satisfied (3), Slightly satisfied (2), Not satisfied (1).
Dynamic Pain as Measured by the Numerical Pain Score (NPS)6, 12, 24, 48 and 72 hours post surgeryTo assess dynamic pain scores, the participant be asked to sit up in bed from supine to sitting, and the NPS will then be recorded. If the participant is ambulating, the dynamic pain score during ambulation (rather during sitting) will be assessed. NPS is a 11-point scale with a higher number indicating more severe pain (total score ranges from 0 to 10).
