February 12, 2018 updated by: Guniz M.Koksal, Istanbul University

Evaluation of the Postoperative Analgesic Efficacy of Catheter Placed Interpectoral Region Via Open Technique in Patients Undergoing Modified Radical Mastectomy

patients undergoing modified radical mastectomy were divided into two groups. patients in catheter group were placed a catheter with open technique by the surgeon in the pectoral area. thirty minutes before extubation %1 lidocain 10 ml, %0.5 bupivacain 10 ml and 10 ml %0.9 sodium chloride were given through the catheter for postoperative analgesia. patients in iv analgesia group were given 100 mg tramadol iv 30 minutes before extubation. visual analog pain scale (VAS) scores, rescue analgesic requirement, complications were recorded and compared between two groups 1, 6, 12, 24 hours and 90 days after surgery.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

patients undergoing modified radical mastectomy were divided into two groups by computer. patients in catheter group were placed a catheter under clavipectoral fascia in the neighbourhood of nervus thoracicus longus, nervus thoracodorsalis, nervus pectoralis lateralis, nervus pectoralis medialis at the 1/3 lateral part of clavicula. solution included 10 ml of %0.5 bupivacain, %1 lidocain, 10 ml %0.9 sodium chloride totally 30 ml were given via the catheter for postoperative analgesia at the end of surgery. patients in iv analgesia group were given 100 mg tramadol iv 30 minutes before extubation. Patients in both groups were given dexketoprofen 50 mg iv if the VAS score was over 4. VAS scores, rescue analgesic requirement and timing, complications were recorded and compared between groups 1, 6, 12, 24 hours and 90 days after surgery.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
VAS scores
Time Frame: 1 hour after operation
patients were asked to give a point between 0 to 10 for their pain level. 0 is no pain, 10 is the strongest pain.
1 hour after operation
VAS scores
Time Frame: 6 hours after operation
patients were asked to give a point between 0 to 10 for their pain level. 0 is no pain, 10 is the strongest pain.
6 hours after operation
VAS scores
Time Frame: 12 hours after operation
patients were asked to give a point between 0 to 10 for their pain level. 0 is no pain, 10 is the strongest pain.
12 hours after operation
VAS scores
Time Frame: 24 hours after operation
patients were asked to give a point between 0 to 10 for their pain level. 0 is no pain, 10 is the strongest pain.
24 hours after operation

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
VAS scores
Time Frame: 3 months after operation
patients were asked to give a point between 0 to 10 for their pain level. 0 is no pain, 10 is the strongest pain.
3 months after operation

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
rescue analgesic requirement
Time Frame: 1, 6, 12 and 24 hours after operation
patients whose VAS scores were over 4 were given 50 mg of dexketoprofen in Group I, 10 ml %0.25 bupivacain in Group II
