resistance. 4 – 8 A prolonged fasting duration prior to surgery might lead to unstable hemodynamics, and might have a potentially harmful influence on cardiac preload. 9 However, there are few reports about the perioperative relationships of body fluid parameters and cardiovascular parameters. Perioperative fluid management is an important consideration during surgery. Assessment tools, such as bioelectrical impedance analysis, are currently available for determining body fluid parameters. 10 – 12 Bioelectrical impedance analysis is a simple and noninvasive

for dental treatment of patients receiving antipsychotic therapy. Thus, the purpose of the present study was to clarify the changes in hemodynamics caused by a drug interaction between adrenaline and an antipsychotic and to evaluate the safety of the combined use of adrenaline with an antipsychotic in an animal study. MATERIALS AND METHODS Animals The protocol of the present study was approved by Okayama University Animal Care and Use Committee (approval number: OKU-2012569). We used male Sprague-Dawley rats (weighing

hospitals with both dentistry and psychiatry departments. The survey suggested that hypotension arising from the concomitant use of antipsychotics and epinephrine-containing lidocaine may be rare. 6 However, no prospective study has assessed the effects of the interaction between epinephrine-containing lidocaine used for dentistry and antipsychotics on hemodynamic parameters. In addition, general anesthesia is often necessary when providing dental care for patients regularly taking antipsychotic drugs, as they may exhibit uncooperative behavior and/or poor compliance

Figure 2.; The blockade effect of propranolol (Pro) on hemodynamic changes by drug interaction between adrenaline (AD) and chlorpromazine (Ch) on mean blood pressure (MBP) (a) and pulse rate (PR) (b) (Ch + saline: n = 4; Ch + Pro + AD: n = 3). AD induced modest hypertension, but did not significantly influence pulse rate change in Pro + Ch–pretreated rats. P values are for between-agent comparisons (vs the value for Ch + saline) at specified time intervals by using 2-way analysis of variance with Bonferroni's post hoc test. Data represent means ± SD.
