The Effect of Pre-Incision Field Block versus Post-Incision Inguinal Wound Infiltration on Postoperative Pain after Paediatric Herniotomy.

Background: The Ilioinguinal/iliohypogastric nerve block has been shown to significantly decrease opioid analgesic requirements and side effects after inguinal herniotomy. We compared the effect of pre-incisional field block with 0.25% bupivacaine and post-incisional wound infiltration with 0.

Modified Mallampati test, thyromental distance and inter-incisor gap are the best predictors of difficult laryngoscopy in West Africans.

Purpose: To determine the ability to predict difficult visualization of the larynx (DVL) from the following preoperative airway predictive indices, in isolation and combination: modified Mallampati test (MMT), thyromental distance (TMD), sternomental distance (SMD), horizontal length of the mandible (HLM) and inter-incisor gap (IIG).

Methods: Three hundred and eighty consecutive patients undergoing general anesthesia were evaluated using the MMT, TMD, SMD, HLM and IIG and the cut-off points for the airway predictors were Mallampati III and IV; < or = 6.5 cm, < or = 13.
