A Phase 4 interventional study of Magnesium Sulfate and Dexmetedomedine in Pain in Pediatric Patients, sponsored by Hagar hassanein refaee. Status unknown at 1 site in Egypt. Open to participants aged 1 Year to 7 Years. Per ClinicalTrials.gov, last updated 2018-03-09.
Sponsored by Hagar hassanein refaee · Phase 4, Interventional, and Prevention
This study will be performed in Abo Elreesh Pediatric Hospital / Cairo University after obtaining approval by the University Ethics Committee, and a written informed consent from the parents or guardians.
Thirty six patients will be randomly assigned using an online randomization program (http://www.randomizer.org) and the sealed envelope method into three groups: Group D (n=12): Dexmetedomidine group. 0.5 ml of dexmetedomidine (2 μg/kg) added to bupivacaine, Group M (n=12) : Magnesium group.0.5 ml of magnesium sulphate (50 mg) added to bupivacaine, Group C (n=12) :Control group.bupivacaine 0.25% diluted in normal saline with total volume of 1 ml/kg.
History regarding previous anesthesia, surgery, any significant medical illness, medications and allergy will be taken for all children who will be enrolled in the study. Complete physical examination and airway assessment will be done. Hemoglobin percentage, blood sugar and coagulation profile will be investigated preoperatively Sedation will be done by giving midazolam (0.2 mg/kg IM).On arrival to the operating room all patients will be monitored by 5 leads electrocardiography (ECG), automated non-invasive blood pressure monitoring (NIBP), and pulse oximetery.
Inhalational induction of anesthesia will be achieved by 8% sevoflurane in 100% oxygen and an appropriate-sized cannula will be inserted. Endotracheal intubation will be performed after which sevoflurane concentration will be reduced to 3%. After hemodynamic stabilization, caudal block will be performed by using beveled needle 18-23 G in the lateral decubitus position by using the loss of resistance technique. The study solutions will be injected caudally slowly with repetitive intermittent aspiration by an anesthesiologist blinded to the test drugs. The inhaled concentration of sevoflurane will be adjusted to achieve hemodynamic changes less than 30% of the preoperative values
Recorded Parameters for the study:
Intraoperative hemodynamic: heart rates (beats/minutes), mean arterial blood pressure (mmHg) after stabilization, before skin incision and every 15 minutes till the end of surgery.
Sedation score: Sedation will be monitored after PACU arrival using Ramsay score with its 0-6 score range.
Pain score (FLACC score) with its 0-10 score range, each patient pain intensity will be assessed at the end of surgery and 12 hours postoperatively.
Time of rescue analgesia (from the time of caudal injection to the time at which FLACC score 4 or more) will be recorded.
Complication secondary to test drugs in the form of toxicity like postoperative nausea and vomiting, respiratory depression, hematoma, bradycardia (HR \<80 BPM) and hypotension (SBP \<70 mmhg+ age in years * 2) and complication secondary to caudal block; infection, hematoma and pain at the site of injection will be recorded.
Total doses of rescue drugs will be calculated for each group.
