Findings suggest that use of dexmedetomidine as an alternative to propofol for sedation of CABG patients post-operatively contributes to reduced mechanical ventilation time, ICU LOS and post-operative LOS. Higher drug costs resulting from the propofol shortage were offset by savings in post-operative room and board costs. Additional savings may be possible by preventing medical complications to the extent possible.

Methohexital, pentobarbital, etomidate, and propofol are viable alternatives to sodium amobarbital for use in the Wada test, but each has shortcomings.

Perioperative pain management has drastically evolved over the years to satisfy current unmet needs. Intermittent delivery of drugs has been replaced by continuous delivery systems involving oral, neuraxial, and peripheral nerve block routes of administration. One current standard of perioperative pain management is an epidural injection of an opioid such as morphine, fentanyl, or hydromorphone, with or without the addition of a local anesthetic, such as bupivacaine. Although this method is extremely effective in controlling pain during the most critical 48-hour period postoperatively, it also has its disadvantages. Risks associated with indwelling epidural catheters include infection, adverse effects, and spinal hematoma. The development of extended- and controlled-release drug delivery systems has revolutionized perioperative pain management. This class of drugs comprises MS Contin (Purdue Pharma LP, Stamford, CT), OxyContin (Purdue Pharma LP), Opana ER (Endo Pharmaceuticals, Chadds Ford, PA), and DepoDur (Endo Pharmaceuticals). There are also phase II trials in progress examining controlled-release formulations of local anesthetics. This review discusses extended- and controlled-release agents administered perioperatively.

We reviewed the records of 49 patients who had 55 episodes of Pneumocystis carinii pneumonia (PCP) from January 1984 to January 1987. Thirty-three patients had acquired immunodeficiency syndrome (AIDS), with the risk groups being homosexual/bisexual practices (26), hemophilia (6), and blood transfusion (1). Fourteen patients had a history of malignancy or chemotherapy and two underwent organ transplantation. Overall response to therapy of PCP was 75% (77% of patients with AIDS, 68% of those with other conditions). All six relapses occurred in patients with AIDS. Both trimethoprim-sulfamethoxazole (TMP-SMX) and pentamidine were associated with a higher rate of toxicity in those patients than in patients with other conditions. A 30% rate of failure due to side effects occurred when TMP-SMX was used as initial therapy, but the combination is considered effective and should be given an adequate therapeutic trial. Pentamidine was an effective alternative for patients who failed with TMP-SMX and for those who failed therapy due to side effects, but was associated with serious toxicities. Our experience was similar in some respects to previous published results from New York and California.
