Comparison of overall pain control effectiveness and selected analgesia-associated symptoms measured preoperatively and at various intervals after surgery among patients randomized to ilioinguinal-iliohypogastric nerve block (Group I) or saline control (Group II).

Overall satisfaction	t = 0	1.03	1.09	0.37
	PACU	1.57	1.46	0.43

Notes: All data tabulated as mean (1 = not present; 2 = present [for pruritus and nausea/emesis], 1 = satisfied; 2 = not satisfied [for overall satisfaction]); t = 0 is 'preoperative', PACU = post-anesthesia recovery unit, h = hours after surgery ¹by Student's t-test
