Comparison between propofol and dexmedetomidine in postoperative sedation after extensive cervical spine surgery.
Summary of "Comparison between propofol and dexmedetomidine in postoperative sedation after extensive cervical spine surgery."
Patients undergoing extensive cervical spine surgery (ECSS) occasionally require emergency reintubation due to postoperative airway complications. To avoid it, an endotracheal tube is retained in patients maintained under sedation overnight. This study was conducted to determine whether dexmedetomidine would be superior in sedative effects to propofol for postoperative sedation after ECSS.
We studied 32 consecutive patients undergoing ECSS who required prophylactic intubation postoperatively under sedation overnight. The patients were randomly divided into two groups. Group D (n = 16) received dexmedetomidine 0.1 μg/kg/min for 10 min as a loading dose, followed by a continuous infusion at 0.4 μg/kg/h. Group P (n = 16) received propofol 0.1 mg/kg/min for 10 min as a loading dose, followed by a continuous infusion at 1 mg/kg/h. All patients received analgesia with buprenorphine. Ramsay sedation scale, extremity movement, and pain intensity were recorded every 2 h. Dexmedetomidine and propofol dosages were adjusted to maintain a desired sedation level. Nursing staff adjusted dopamine to maintain systolic blood pressure >100 mmHg and administered atropine when the heart rate was <50 bpm.
The proportions of adequate sedation level, movement, and pain status were similar between groups. In group D, heart rates were lower, frequency of atropine use was greater, and dopamine dose was higher than in group P.
Both sedatives are efficacious after ECSS; however, dexmedetomidine decreased heart rate and required higher dose of dopamine.

Medical and Biotech [MESH] Definitions
An intravenous anesthetic agent which has the advantage of a very rapid onset after infusion or bolus injection plus a very short recovery period of a couple of minutes. (From Smith and Reynard, Textbook of Pharmacology, 1992, 1st ed, p206). Propofol has been used as ANTICONVULSANTS and ANTIEMETICS.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
A nonsteroidal anti-inflammatory agent with potent analgesic and antiarthritic properties. It has been shown to be effective in the treatment of OSTEOARTHRITIS; RHEUMATOID ARTHRITIS; ankylosing SPONDYLITIS; and in the alleviation of postoperative pain (PAIN, POSTOPERATIVE).
Abdominal symptoms after removal of the GALLBLADDER. The common postoperative symptoms are often the same as those present before the operation, such as COLIC, bloating, NAUSEA, and VOMITING. There is pain on palpation of the right upper quadrant and sometimes JAUNDICE. The term is often used, inaccurately, to describe such postoperative symptoms not due to gallbladder removal.
A selective inhibitor of RECEPTORS, ADRENERGIC ALPHA-2 that has analgesic and sedative properties. MEDETOMIDINE is the other racemic form.

Acetylcholine plays an important role as a neurotransmitter in the central nervous system with involvement in both sleep and arousal. Dexmedetomidine, midazolam, and propofol are widely used for sedat...
BACKGROUND: Prolonged or complex endoscopic procedures are frequently performed under deep sedation. However, no studies of therapeutic ERCP have yet compared the use of balanced propofol sedation (BP...
