Randomized Controlled Trial Clinical TrialBupivacaine wound infiltration in thyroid surgery reduces postoperative pain and opioid demand.
Control of postoperative pain is an important element in preventing the modification of the excitability of the dorsal horn neurons. We studied the efficacy of bupivacaine 0.5% wound infiltration for postoperative pain management following thyroid surgery. Forty consecutive ASA I-II patients, scheduled for thyroidectomy, were assigned randomly to two groups. ⋯ In comparison, 18 patients (90%) in group II received morphine during the first postoperative day. The local injection of bupivacaine corresponds to a block of the superficial branches of the cervical plexus. This study demonstrated a simple, efficient and safe way to reduce pain perception following a thyroidectomy.

Randomized Controlled Trial Clinical TrialThoracic epidural analgesia in aortocoronary bypass surgery. I: Haemodynamic effects.
Tachycardia and hypertension may cause myocardial ischaemia in patients with coronary heart disease going through major surgery. Thoracic epidural analgesia (TEA) has been reported to be beneficial in this situation. The haemodynamic effects of TEA in aortocoronary bypass surgery were investigated in 30 male patients < 65 years old and with ejection fraction > 0.5. ⋯ More ketanserin to HF group patients and methoxamine to epidural group patients were given. After bypass heart rate increased in all groups. Lower MAP 0.5 h after bypass and higher filling pressures in the early post bypass period in the epidural groups, most pronounced in the HF+TEA group, were noted.(ABSTRACT TRUNCATED AT 250 WORDS)
