Study summary

Tonsilloadenoidectomy operations in pediatric patients cause local pain. Especially, in order to reduce the need for narcotic painkillers, to ensure patient compliance and well-being, and to provide better quality pain management regional pain prevention methods, which are included in the guidelines, are applied to these patients. One of these methods is glossopharyngeal nerve block. This block is the blocks that the investigators routinely apply to patients in different uses for the purpose of pain management before/after adenotonsillectomy operations in the clinic. The investigators plan to apply the glossopharyngeal nerve card that the investigators will make in different doses and follow the patient's pain and stomach volume after the surgery.

Read the detailed description

In this study, a group of patients who will undergo adenotonsillectomy surgery will be performed glossopharyngeal nerve block with 0,2 milliliter/kilogram (ml/kg) %0.125 bupivacaine bilaterally; the other group will be performed glossopharyngeal nerve block with 0,2 milliliter/kilogram %0.25 bupivacaine bilaterally. Postoperatively, patient's pain level, stomach volume, possible undesirable results, hospital stay, and satisfaction level will be monitored and recorded. The results will be compared. After reading and signing the informed consent form, the block will be applied under general anesthesia in the operating room with monitorization, and then the operation will be performed under general anesthesia. Post-operative follow-up will be done.

What researchers measure

Primary outcomes

  1. The Face, Legs, Activity, Cry, Consolability (FLACC) Pain Score at Rest at 30 Minutes Postoperatively

    The Face, Legs, Activity, Cry, Consolability (FLACC) scale is used to assess pain. The total score ranges from 0 to 10, with 0 indicating no pain and higher scores indicating greater pain intensity. Pain scores are assessed separately at rest and during swallowing.

    Time frame: 30 Minutes Postoperatively

  2. The Face, Legs, Activity, Cry, Consolability (FLACC) Pain Score During Swallowing at 30 Minutes Postoperatively

    The Face, Legs, Activity, Cry, Consolability (FLACC) scale is used to assess pain. The total score ranges from 0 to 10, with 0 indicating no pain and higher scores indicating greater pain intensity. Pain scores are assessed separately at rest and during swallowing.

    Time frame: 30 Minutes Postoperatively

  3. The Face, Legs, Activity, Cry, Consolability (FLACC) Pain Score at Rest at 60 Minutes Postoperatively
