Comparison of the effectiveness of intravenous injection of Ketamine and Ondansetron in the prevention of the post-operative shivering in Cesarean Section under spinal anesthesia
Comparison of the effect of prophylactic injections of ketamine and Ondansetrone on shivering after cesarean section under spinal anesthesia
Design
Clinical trial with a control group, with parallel groups, double-blind, randomized, phase 3 on 121 patients. Randomization is done using Random Allocation software.
Settings and conduct
This is a randomized double-blind clinical trial in which the target population of pregnant women is candidates for cesarean section under spinal anesthesia at Beheshti Hospital in Isfahan. Patients are randomly assigned to three groups C, B, and A, and each group is randomly assigned to one of three intervention groups, and the patient's vital signs are monitored before, during, and after surgery. The intervention groups are coded, so the injecting person, the clinical caregiver, and the patient are unaware of the injected intervention and are blind.
Participants/Inclusion and exclusion criteria
Pregnant women in grades I and ASA II, candidates for cesarean section under spinal anesthesia, can be screened if they have no history of high blood pressure, mental illness, heart problems with EF <60%, or kidney problems with GFR <60.
Intervention groups
Intervention group A: 4 mg of Ondansetron,
Intervention Group B; 0.5 mg of ketamine per kilogram of body weight and C intervention group; Normal saline as a placebo is injected into the patient immediately after clamping of the umbilical cord.
Main outcome variables

Randomization (investigator's opinion)
Randomized
Randomization description
Randomization is done in a simple way so that the names of patients enter the randomization software (https://random-allocation-software.software.informer.com/2.0/) if they have the necessary conditions and according to the time of entry. software Randomly assign numbers to each patient, and based on these numbers, patients enter one of the intervention or control groups so that their number reaches the required number in each group.
Blinding (investigator's opinion)
Double blinded
Blinding description
The drugs and placebo are packaged in the same form with the same volume and coded, and are randomly distributed among patients so
the attending, the clinical caregiver, and the evaluator do not notice the type of medication.
