Postoperative Pain Management
Conditions
Brief summary
Ultrasound as a technique is safe, readily available, quick and portable allowing more accuracy of different regional blocks and local infiltration. It allows imaging of the mouth, oropharynx, infrahyoid structures, larynx, vocal cords, and trachea. Recently, ultrasound has been shown to improve accuracy in ultrasound guided block with local anesthetic infiltration. The objective of our study is to compare the effect of pre-emptive trans-oral ultrasound guided peritonsillar infiltration versus trans-cutaneous ultrasound (US) guided peritonsillar infiltration with bupivacaine for post-tonsillectomy analgesia, on surgical field, and surgeon satisfaction(intra-operative reactionary bleeding). Materials and Methods: the patients will be admitted for tonsillectomy at ENT department of the Al- Azhar university hospitals. The patients' ages between 3 to 15 years. Patients will be divided into Cutaneous group: patients will be submitted to Trans-cutaneous ultrasound guided peritonsillar infiltration with bupivacaine, and Oral group: patients will be submitted to Trans-oral ultrasound guided peritonsillar infiltration with bupivacaine.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Surgical field (intra-operative reactionary bleeding and/or muscle tear) | time of surgery | * Iintra-operative reactionary bleeding and/or muscle tear assessment by number of soaked gauze per 20 min (per tonsil) (3 soaked gauze per 20 min (per tonsil) = no reactionary bleeding (0 point), 6 soaked gauze per 20 min (per tonsil) = mild bleeding (1 point) and 10 soaked gauze or more per 20 min (per tonsil) = moderate to severe bleeding (2 points). * Dissection time assessment (dissection time 10 min or less per tonsil = no bleeding (0 point), dissection time 20 min per tonsil = mild bleeding (1 point) and dissection time 30 min or more per tonsil = moderate to severe bleeding (2 points). |
| Surgeon satisfaction | time of surgery | Direct surgeon questionnaire assessment about bleeding and surgical field (full satisfaction= no bleeding (0 point), fair satisfaction= mild bleeding (1point), and poor satisfaction= moderate to severe bleeding (2 points) |
