Analgesic efficacy of ultrasound-guided rhomboid intercostal block versus serratus plane block in modified radical mastectomy: a prospective randomized controlled study.

Background: This research aimed to assess the analgesic efficacy of ultrasound-guided rhomboid intercostal block (RIB) or serratus plane block (SPB) versus IV opioid among modified radical mastectomy (MRM) patients.

Methods: One hundred and five female patients aged 18-65 years with American Society of Anesthesiologists (ASA) physical status II-III scheduled for unilateral MRM were randomly allocated into three equal groups: 1) control group (received IV basal analgesia); 2) SPB group (received ipsilateral SPB); and 3) RIB group (received ipsilateral RIB).

Results: Visual Analogue Scale (VAS) was significantly increased in control group compared to SPB group at Post-Anesthesia Care Unit (PACU) (1 [1-2], 0 [0-1]), 2 h (4 [3-4], 0 [0-1]), and 4 h (3 [3-4], 2 [1-2]) postoperative in control and SPB groups, respectively; and in comparison with RIB group at PACU (0 [0-1]), 2 h (1 [0-1]), 4 h, (1 [1-2]), 6 h (1 [1-2]), and 8 h (2 [1-2]), postoperative.

Preoperative peritonsillar infiltration of dexamethasone and levobupivacaine reduces pediatric post-tonsillectomy pain: a double-blind prospective randomized clinical trial.

Background: Preoperative corticosteroids reduce post-tonsillectomy morbidities. The present study was performed to compare the effect of peritonsillar dexamethasone infiltration to intravenous injection together with peritonsillar levobupivacaine infiltration before tonsillectomy on postoperative pain in children.

Methods: One hundred twenty children, ASA I-II, aged 6-12 years, scheduled for adenotonsillectomy were enrolled in the study.
