BACKGROUND: The most commonly used drug for total intravenous anesthesia (TIVA) is ketamine which results in cardiovascular stimulation. AIMS: The primary aim of this study was to assess the effect of oral clonidine premedication on attenuating the hemodynamic responses following ketamine administration. SETTINGS AND DESIGNS: This was a prospective, observational, comparative study conducted in a tertiary care institution. SUBJECTS AND METHODS: A total of 40 female patients aged 18-55 years who were posted for elective short gynecological procedures under TIVA were recruited for this study...

Limited data are available on hemodynamic responses to anesthetic protocols in wild-born chimpanzees (Pan troglodytes). Accordingly, this study characterized the heart rate (HR) and blood pressure responses to four anesthetic protocols in 176 clinically healthy, wild-born chimpanzees undergoing routine health assessments. Animals were anesthetized with medetomidine-ketamine (MK) (n = 101), tiletamine-zolazepam (TZ) (n = 30), tiletamine-zolazepam-medetomidine (TZM) (n = 24), or medetomidine-ketamine (maintained with isoflurane) (MKI) (n = 21)...

We investigated the incidence of post-intubation hypotension (PIH) in hemodynamically stable patients with STEMI requiring rapid sequences intubation (RSI) and medicated with ketamine or midazolam as induction agent. STEMI patients admitted between 1st January 2009 and 1st January 2017 who did not receive any type of inotropic support before the endotracheal intubation (ETI) was reviewed. PIH was defined as a reduction greater than 20% or a drop of systolic blood pressure (SBP) below 90 mmHg within 10 min from the administration of the induction agent [ketamine (1 mg/kg) or midazolam (0...

Transcranial motor evoked potentials (TcMEPs) monitor the integrity of the spinal cord during spine surgery. Propofol-based anesthesia is favored in order to enhance TcMEP quality. During intraoperative hemorrhage, TcMEP amplitudes may be reduced. The serum concentration of propofol may increase during hemorrhage. No study has determined whether changes in TcMEPs due to hemorrhage are related to changes in propofol blood levels. We monitored TcMEPs, mean arterial pressure (MAP), and cardiac output (CO) and hemoglobin in pigs (n = 6) undergoing controlled progressive hemorrhage during a standardized anesthetic with infusions of propofol, ketamine, and fentanyl...

OBJECTIVES: The aim of the present study was to compare the effects of intranasal ketamine and midazolam on behavior of 3-6 year-old children during dental treatments. MATERIALS AND METHODS: In this randomized cross-over clinical trial, 17 uncooperative children requiring at least two dental treatments were selected and randomly received ketamine (0.5mg/kg) or midazolam (0.2mg/kg) prior to treatment. The other medication was used in the next visit. The children's behavioral pattern was determined according to the Houpt's scale regarding sleep, movement, crying and overall behavior...

BACKGROUND: In mammals, homeostasis and survival are dependent on effective trans-membrane movement of ions and enzyme function, which are labile to extreme acid-base changes, but operate efficiently within a narrow regulated pH range. Research in patients demonstrating a pH shifts outside the narrow regulated range decreased the cardiac output and systemic vascular resistance and altered the oxygen binding to haemoglobin. These cardiopulmonary observations may be applicable to the risks associated with anaesthesia and performance of wildlife ungulates on game farms...

This article reviews fluid therapy and medications in pediatric trauma. For resuscitation in the setting of hemorrhagic shock, isotonic crystalloid solution is the first-line agent of choice. Colloid solutions offer no additional benefit, introduce possible increased risks and cost more than crystalloids. Blood products, starting with pRBCs, should be introduced after 20-40 ml/kg of crystalloid has been administered if there is ongoing need for volume replacement. The use of a massive transfusion protocol of 1:1:1 (if >30 kg) or 30:20:20 (if <30 kg) of pRBCs:FFP:platelets is suggested after an initial 30 ml/kg of pRBcs have been administered...

BACKGROUND: This study was designed to compare the effects of resuscitation with cold and warm fluid on survival time, rate and volume of hemorrhage, hemodynamics, hypothermia, coagulopathy, acid-base balance, hematocrit, lactate, and base deficit during uncontrolled hemorrhagic shock (HS) model in rats. METHODS: HS model was created with splenic vascular and parenchymal injury in 29 rats under ketamine and xylazine anesthesia. Thirty minutes after the hemorrhage, the rats were randomized to receive 14...

Six clinically healthy captive cheetahs ( Acinonyx jubatus ) were anesthetized twice using two different drug combinations to investigate if blood pressure and kidney blood flow are affected by medetomidine dosage. Protocol KM (2.0 mg/kg ketamine and 0.05 mg/kg medetomidine) was compared with protocol KMM (2.0 mg/kg ketamine, 0.02 mg/kg medetomidine, and 0.1 mg/kg midazolam). Heart rate (HR), respiratory rate (RR), body temperature, end-tidal carbon dioxide pressure (ETCO2), and anesthetic depth were monitored every 10 min...

Perioperative hypertension is a phenomenon in which a surgical patient's blood pressure temporarily increases throughout the preoperative and postoperative periods and remains high until the patient's condition stabilizes. This phenomenon requires immediate treatment not only because it is observed in a majority of patients who are not diagnosed with high blood pressure, but also because occurs in patients with underlying essential hypertension who show a sharp increase in their blood pressure. The most common complication following facelift surgery is hematoma, and the most critical risk factor that causes hematoma is elevated systolic blood pressure...

BACKGROUND: The needle puncture produces discomfort during regional anesthesia. Sedation and local anesthesia are used to promote analgesia and amnesia. The main objective of this study was to compare the efficacy of four subanesthetic doses of dextroketamine for pain relief during brachial plexus block via the posterior approach.

BACKGROUND: Methoxetamine and 3-methoxy-phencyclidine are novel arylcyclohexylamines whose use and clinical toxicity are poorly reported in the medical literature. We report a case of analytically confirmed use of both methoxetamine and 3-methoxy-phencyclidine. CASE REPORT: A 27-year-old male presented 10 hours after insufflating an Internet-obtained powder. He was hypertensive, tachycardic, and demonstrated dissociated affect, a delayed verbal response to questions, ataxia, and vertical nystagmus...

REVIEW
Chittaranjan Andrade
Ketamine is an anesthetic drug that is also used for off-label indications such as the mediation of analgesia and sedation in various settings. It is additionally recognized as an agent with antidepressant potential. For depression, it is most commonly administered as a slow intravenous infusion in subanesthetic doses (usually 0.5 mg/kg). As an antidepressant, is strikingly different from conventional antidepressant drugs in that it brings about rapid and marked attenuation of depressive symptoms even in patients with refractory depression...

The N-methyl-D-aspartate receptor antagonist ketamine has rapid onset activity in treatment-resistant depression, post-traumatic stress disorder and obsessive compulsive disorder. Due to similarities in brain network activity in depression and anxiety disorders, we hypothesized that ketamine might also be active in other refractory anxiety disorders. We evaluated the efficacy and safety of ketamine in 12 patients with refractory generalized anxiety disorder and/or social anxiety disorder who were not currently depressed, using an ascending single dose study design (0...

BACKGROUND AND AIMS: Prolonged mechanical ventilation after cardiac surgery is associated with serious complications that increase morbidity and mortality. The present study was designed to compare ketamine-propofol (KP) and ketamine-dexmedetomidine (KD) combinations for sedation and analgesia in patients after coronary artery bypass graft (CABG) surgery as regards hemodynamics, total fentanyl dose, time of weaning from mechanical ventilation, time of extubation, and any adverse outcome...
