Brief summary

A multicenter, randomized, open-label, active controlled pragmatic clinical trial that evaluates the safety and efficacy of S (+) -ketamine for postoperative acute pain in children in perioperative settings.

Detailed description

Children often suffer acute pain,awakening delirium, anxiety and depression after operation which may affect the recovery of children. S (+) - ketamine has been described to decrease acute pain and opioid consumption,but it needs to confirm for chinese children undergoing surgery. Objective: To evaluate the analgesic effect of perioperative administration of S (+) - ketamine on postoperative acute pain in children undergoing surgery, and explore the effects of S (+) - ketamine on postoperative awakening delirium, postoperative anxiety and depression mood ,as well find the best usage, including dose, timing, compatibility, and type of operation.

Interventions

In principle, there are no specific restrictions on the dosage, mode of administration, timing, and compatibility of S-ketamine hydrochloride injection, but the recommended dosage is given, which is lower than the dosage specified in the instructions. Recommended use and dosage of S (+)-Ketamine: 1. Intravenous injection:Bolus intravenous injection before skin incision, the dose is 0.1\ 0.25 mg/kg; Bolus intravenous injection (dose 0.1\ 0.25 mg/kg) before skin incision + continuous intravenous infusion (dose of 0.1\ 0.25 mg/kg/h) during operation; Continuous intravenous infusion after surgery with a dose of 0.02\ 0.1 mg/kg/h for 24\ 48 h. 2. Intramuscular injection:The dose is 2\ 4 mg/kg.

DRUGConventional therapy

Receiving conventional therapy without S (+)-Ketamine hydrochloride injection. There is no restrictions in drugs, doses and incompatibility, the researchers can choose appropriate medication regimens based on clinical practice, but other NMDA receptor antagonists are not be allowed to use, such as dextromethorphan and amantadine.

Design outcomes

Primary

MeasureTime frameDescription
The area under the broken line of FLACC scale scoreHour 0-48 after surgeryOnly for children aged 0\ 7 years. The score of FLACC Scale is 0-10, the higher the score, the more severe the pain.
The area under the broken line of Numerical Rating Scale scoreHour 0-48 after surgeryOnly for children aged 8\ 17years. The score of Numerical Rating Scale(NRS) is 0-10, the higher the score, the more severe the pain.
Opioid consumptionHour 0-48 after surgeryTotal opioid consumption(conversion to equivalent morphine)

Other

MeasureTime frameDescription
The incidence of rescue analgesiaHour 0-48 after surgeryRescue analgesia refers to the analgesia according to the patient's or guardian's requirements in addition to routine postoperative analgesia.
Recovery timeDay 0The time from the end of the operation to recovery(can be awakened)
The incidence of emergence deliriumDay 0Only for children aged 0-7 years. Evaluating by the Pediatric Emergence Delirium Rating Scale(PAED) ,the score of the scale is 0\ 20, when the total score is greater than 10, it is considered that the child has delirium.The scale will be evaluated 10minutes, 20minutes, 30minutes after extubation.
The incidence of unexpected intraoperative eventsIntraoperativeUnexpected events during operation include intraoperative cough, laryngeal spasm, body movement, tachycardia, decreased oxygen saturation, respiratory depression, bradycardia, hypertension and hypotension.
FLACC scale scoreHour 0-48 after surgeryOnly for children aged 0\ 7 years. The score of FLACC Scale is 0-10, the higher the score, the more severe the pain. 8≤Age ≤17 years: NRS pain score at 2h, 4h, 24h, 48h after surgery.
Children's Depression Inventory(CDI) scoreHour 48 after surgeryOnly for children aged 8\ 17.Children's Depression Inventory(CDI) scale include 27 questions ,from 0 to 54pionts, the higher the score, the more severe the depressive symptoms.
Hospital Anxiety and Depression Scale(HAD)scoreHour 48 after surgeryOnly for children aged 14\ 17.Hospital Anxiety and Depression Scale(HAD)include anxiety measure(7 questions,0-21pionts) and depression measure(7 questions,0-21pionts),the higher the score, the more severe the symptoms.
Pharmacoeconomic indicatorsHour 48 after surgeryCalculating incremental cost-effectiveness ratio (ICER)based on cost-effectiveness analysis.
The incidence of adverse events after surgeryHour 0-48 after surgeryThe incidence of adverse events from the end of the operation to 48h after surgery. Including nausea, vomiting, increased secretions, dizziness, oversedation, infection,anesthetic awareness, nightmares, restlessness, pruritus, disorientation, delirium, respiratory depression, diplopia, diarrhea, intestinal obstruction, urinary retention, gastroesophageal reflux, constipation, chills, hallucinations, etc.
Numerical Rating Scale scoreHour 0-48 after surgeryOnly for children aged 8\ 17years. The score of Numerical Rating Scale(NRS) is 0-10, the higher the score, the more severe the pain.
Time of first rescue analgesiaHour 0-48 after surgeryThe time from the end of the operation to the first rescue analgesics after the operation. Rescue analgesia refers to the analgesia according to the patient's or guardian's requirements in addition to routine postoperative analgesia.
