Several drugs are used intravenously, alone or in combination with other drugs, to achieve an anesthetic state (as components of balanced anesthesia) or to sedate patients in intensive care units who must be mechanically ventilated. These drugs include the following (1) barbiturates (thiopental, methohexital) (2) benzodiazepines (midazolam, diazepam) (3) opioid analgesics (morphine, fentanyl, sufentanil, alfentanil, remifentanil) (4) propofol (5) ketamine and (6) miscellaneous drugs (droperidol, etomidate, dexmedetomidine). Figure 25-2 shows the structures of...

Diltiazem caused a 43% mean increase in the half-life of midazolam in 30 patients who underwent coronary artery bypass grafting (57). Similar effects were observed with alfentanil. The proposed mechanism was diltiazem-induced inhibition of benzodiazepine metabolism by CYP3A. Patients taking diltiazem had delayed early postoperative recovery as a result. 

Sedation in critical care units is used to reduce patient anxiety and improve tolerance to tracheal tubes and mechanical ventilation. Whenever possible, patients are sedated only to a level that allows them to open their eyes to verbal command oversedation is harmful. Commonly used drugs include propofol and midazolam, and opioids such as fentanyl, alfentanil, or morphine.

A study in patients undergoing an abdominal hystereetomy under alfentanil and midazolam anaesthesia found that although the pharmaeokinet-ies of midazolam were unehanged, postoperative sedation was more pronouneed, when eompared with a group of patients that did not reeeive alfentanil. ...

Opioid analgesic drugs (OADs), particularly fentanyl and its analogs alfentanil, remifentanil, and sufentanil, are extensively used for anesthesia and analgesia. Administration of intravenous hypnotics and OADs as a high dose opioid, low dose hypnotic (usually a benzodiazepine such as midazolam) has found wide application in cardiac anesthesia and to produce procedural sedation for endoscopy, catheterizations, and a variety of other surgical procedures where sedation and...
