Trial Outcomes & Findings for Selective Intraoperative Administration of Local Anesthesia in Breast Reconstruction (NCT NCT02525718)

NCT ID: NCT02525718

Last Updated: 2019-08-14

Results Overview

The primary outcome measure is a well-validated and widely used survey measuring the quality of recovery from anesthesia entitled the "Global 40 Item Quality of Recovery" survey. This is a 40 question survey administered to patients to allow them to rate their quality of recovery along a number of different dimensions, including emotional state, physical comfort, psychological support, physical independence, and pain. The score ranges from 40 to 200, with 40 representing a very poor overall quality of recovery and 200 representing the best possible recovery. The following reference explains the Global 40 Item Quality of Recovery survey in detail: Myles, P.S., et al., Validity and reliability of a postoperative quality of recovery score: the QoR-40.

Placebo
Subjects will be randomly selected to receive saline (placebo), administered to the breast area to cover the intercostal nerves supplying the breast tissue during surgery. Saline: If randomized to this arm, subjects will receive an intraoperative injection of saline. (2.5 mg/ml)
0.25 % Bupivacaine w/ Epinephrine & 4mg Dexamethasone
Subjects will be randomly selected to receive selective block with a local anesthetic solution containing 0.25 % bupivacaine (2.5 mg/ml) with 1:100,000 epinephrine and 4 mg dexamethasone. The injection will be performed in certain locations of the breast area to cover the intercostal nerves supplying the breast tissue. Subjects will be randomly selected to receive the local anesthetic solution containing 0.25 % bupivacaine (2.5 mg/ml) with 1:100,000 epinephrine and 4 mg dexamethasoneadministered to the breast area to cover the intercostal nerves supplying the breast tissue during surgery. 0.25 % bupivacaine (2.5 mg/ml) w/ 1:100,000 epinephrine \& 4 mg dexamethasone: If randomized to this arm, subjects will receive a selective block with a local anesthetic solution containing 0.25 % bupivacaine. (2.5 mg/ml) with 1:100,000 epinephrine and 4 mg dexamethasone intraoperatively.

Quality of Recovery Score
165 score on a scale
Interval 143.0 to 179.0
169 score on a scale
Interval 155.0 to 182.0

SECONDARY outcome

Timeframe: 24 hrs

A study-specific pain form was provided to the patient and nursing staff that consisted of standard visual analogue scale (VAS) for patients to rate their pain level. Pain level was rated as a categorical level from 0 to 10, in 1 unit increments, with 0 being "no pain at all" and 10 being "worst pain imaginable." Thus a total of 10 pain grades were possible.

Interval 3.0 to 6.0

SECONDARY outcome

Timeframe: 24 hrs

Total opioid consumption in the first 24 hrs of recovery after surgery as measured in "morphine equivalents." This involves converting the dose of a non-morphine narcotic (e.g. IV hydromorphone or oral hydrocodone) into the equi-analgesic dose of morphine, so that the total amount of narcotic utilized by the patient can be compared. This is a standard technique for comparison utilized in the pain management literature.
