Preoperative management of medications for psychiatric disorders.

Perioperative medication management is a complex topic. Physicians working in the perioperative space are frequently called upon to make decisions regarding continuing or stopping certain medications. For patients with psychiatric disorders, the overwhelming recommendation is to continue therapy with heightened awareness of anesthesiologists regarding potential side effects or medication interactions.

Pain and genetics.

PURPOSE OF REVIEW: Pain management is one of the most important fields in the practice of anesthesiology. The concept that genes involved in the absorption, metabolism, and receptor affinity of analgesics are critical to a drug's efficacy is becoming widely accepted. A review of pharmacogenomics and how it affects the response to analgesics, mainly opioids, is presented in this article. RECENT FINDINGS: As the field of pharmacogenomics expands, more and more candidate genes are being evaluated. Genes related to the µ-opioid receptor, ATP-binding cassette subfamily B, catechol-O-methyltransferase, and cytochrome 2D6 currently show promise in helping predict the gene phenotype. Recent studies have also focused on the interleukin-1 receptor antagonist and the melanocortin-1 receptor, further adding to the picture. SUMMARY: Through increased knowledge in the area of pharmacogenomics, it is hoped that that treatment of pain will move into the realm of personalized medicine. This should result in greater treatment success and a reduction of significant side-effects.
