About this study
Official title: Comparative Study of Ropivacaine and Ropivacaine With Dexmeditomedine in Transversus Abdominis Plane (TAP) Block for Post-operative Analgesia in Patients Undergoing Cesarean Sections
Comparative study of Ropivacaine and Ropivacaine with dexmedetomidine in transversus abdominis plane (TAP) block for post-operative analgesia in patients undergoing Caesarean Section.
Read the detailed description
Patients satisfying inclusion criteria will receive Subarachnoid Block with Bupivacaine Heavy 0.5% (11 mg/2.2 ml) with 25 micrograms of fentanyl. Routine NPO protocols will be followed. At the end of the procedure, bilateral TAP block will be performed using Landmark Technique in Triangle of Petit with 2 inches 24 G needle.
Patients would receive 75 mg of intramuscular diclofenac sodium immediately on shifting to the postoperative care unit (PACU) and a second dose 12 hours later. The time after the TAP block when rescue analgesia was first sought, total dose of required morphine in 24 hours postoperatively, its adverse effects like pruritus, nausea and vomiting will be recorded. VAS will be used to assess post-operative pain (VAS; where 0 = no pain and 10 = worst imaginable pain) during rest and on coughing.
Rescue analgesia would be provided with 6 mg of intravenous morphine and additional doses of 3 mg at 10 minutes interval till VAS was less than 3 or in case of development of adverse effects such as nausea and/or vomiting, respiratory depression (SpO2 <92%, ventilatory frequency rate <10), or occurrence of deep sedation (eyes closed >3 min, Ramsay Score RS >2). An RS on a 6-point scale was used (1=anxious and agitated patient; 2=cooperative patient; 3=asleep patient, brisk response to loud voice; 4=asleep patient, sluggish response to loud voice; 5=no response to loud voice; score of 6=no response to pain). In PACU and in first 24 h post-operatively, MAP, HR, VAS (at rest and on coughing), nausea and vomiting, sedation score (RS) will be recorded on admission to PACU and at 1,4, 8, 12, 18 and 24 hours post-operatively by an observer who will be unaware of the study protocol.
Patients will we assessed on a 5 point scale at the end of 24 hours on the quality of postoperative analgesia. Nausea and vomiting will be recorded using a categorical scoring system (0 = none, 1 = nausea, 2 = retching, 3 = vomiting). IV Metoclopramide 10 mg bolus will be offered for any patient with a score >/=1.

What does the primary outcome measure?
The Time After the TAP Block When Rescue Analgesia Was First Sought (time frame: 24 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jul 2016.
