Comparison of circulatory and respiratory responses between supplementary epidural buprenorphine and eptazocine administration during and immediately after total intravenous anesthesia.
Opioid supplements are often required in total intravenous anesthesia (TIVA). Most ϰ-opiate receptors are found in the spinal cord, wherea μ-opiate receptors are widespread throughout the brain and spinal cord. Buprenorphine has a strong μ-action with a minute ϰ-action, while eptazocine stimulates ϰ-receptors only. ⋯ A significant analgesic effect (P<0.01) of epidural eptazocine without circulatory and respiratory depression was observed. With epidural buprenorphine, circulatory and respiratory depression during and immediately after anesthesia were significant (P<0.05). These results suggest that medullary μ-stimulation by an epidural opioid induces circulatory (hypervagotonicity and hypervagosensitivity) and respiratory depression, while ϰ-stimulation produces only minimal effects on circulatory and respiratory systems.

Randomized Controlled Trial Clinical TrialA controlled, randomized, double-blind study of ketorolac for postoperative analgesia after plastic surgery.
The present study was designed to evaluate the efficacy and safety of ketorolac compared with metamizol (Nolotil) in the control of pain after plastic surgery. Almost no literature exists on postoperative pain control in this specialty. A multiple-dose, randomized, double-blind study of parallel design was carried out. ⋯ Ketorolac and metamizol were found to be equally safe and effective in reducing postoperative pain after plastic surgery. It should be noted that 52% of patients in the ketorolac group and 48% in the metamizol group considered their postoperative analgesia to be very good. Nevertheless, for surgical procedures or for patients in whom postoperative hematoma formation is a particular concern, ketorolac probably should not be used.

The medical profession is besieged by concerns about cost containment. This in turn has focused attention on the use of ambulatory surgical facilities. However, the costs of hospital outpatient surgery programs usually prevent them from being competitive when compared with the costs of using office surgical facilities. ⋯ A death occurred in 1 in 57,000 cases (0.0017 percent). The overall risk is comparable in an accredited office (plastic surgical facility) and in a free-standing or hospital ambulatory surgical facility. This study documents an excellent safety record for plastic surgery done in accredited office surgical facilities by board-certified plastic surgeons.
