Transient hyperkalemia is well known to occur in man following intravenous administration of succinylcholine chloride. To study on change of the serum level of K+, Na+ & Cl- after injection of succinylcholine in healthy adults, physical status 1 or 2 adopted by the American society of Anesthesiologists, we studied in two groups: pentothal sodium-succinylcholine injection group (group 1) as control, flaxedil-pentothal sodium-succinylcholine injetion group(group 2) as experimental. The following results were obtained: 1. Serum K+ was slightly increased in both groups, 2mEq/L at 3rd minute in control group, 2mEq/L at 1st minute in experimental group after succinylcholine injection, but no statistical significance was noticed in either group. 2. Serum Na+ was decreased 3 mEq/L immediately after pentothal sodium injection and then sliyhtly increased until 10th minute in control group. In experimental group lower level than control was observed until 15th minute, with the maximum decrease of 7mEq/L at 5th minute. But no statistical significance was noticed in either group. 3. Serum Cl was slightly decreased until 10th minute with the maximum decrease of 4mEq/L at 5th minute in control group. In experimental group, it was slightly increased until 5th minute. But no significance was noticed in either group.

BACKGROUND: Rocuronium is suitable for short operations and rapidly controlling the airway on account of its rapid onset and intermediate action. However, the intravenous administration of rocuronium can cause pain and withdrawal movement in children. This study evaluated the effect of diluting rocuronium from 10 mg/ml to 1 or 0.67 mg/ml with 0.9% NaCl on the withdrawal response associated with the intravenous administration of rocuronium with the intubation dose. METHODS: Ninety pediatric patients undergoing general anesthesia were randomized into one of three groups; Group OR (only rocuronium 0.6 mg/kg, n = 30), Group SR10 (rocuronium 0.6 mg/kg diluted with 0.9% NaCl to 1 mg/ml, n = 30), Group SR15 (rocuronium 0.6 mg/kg diluted with 0.9% NaCl to 0.67 mg/ml, n = 30). After the loss of consciousness by a thiopental sodium 5 mg/kg injection, the patients from each group received the 0.6 mg/kg premixed rocuronium, respectively. Patients' withdrawal response to the injection were graded using a 4-point scale (Grade 0, 1, 2, 3). RESULTS: The incidence and the intensity of the withdrawal response were significantly lower in the SR10 and SR15 groups than in the OR group (P < 0.05). In the SR15 group, the intensity of the withdrawal response was under grade 2 in all patients. CONCLUSIONS: Diluting rocuronium to 0.67 mg/ml is a simple and effective method for preventing withdrawal movements during an intravenous rocuronium injection.

This study was undertken to estimate the induction time, hemodynamic responses and local venous complications after intravenous administration of the midazolam, the water-soluble benzodiazepine derivative, comparing with those of the thipental, as an induction agent. Sixty ASA Class I or II surgical patients were divided into two groups: I and II, and were given 5 mg/kg thiopental sodium and 0.15 mg/kg midazolam hydrochloride, respectively. The results obtained were as follows; 1) The induction timeQoss of palpebral reflex) of the group II(88.7+/-41.8 seconds)was longer than those of the group I (19.5+/-3.7 seeonds). 2) The magnitude of fall in the systolic blood presure, 1 and 2 minute after intravenous administration of the induction agents observed in the group II was smaller than those observed in the group I compared with the pre-induction valuea But other parameters did not change significantly compsred with the pre-induction values in both groups. 3) In five patients of the group I, they complained of pain on the injection, but no patient of the group II complained of it. There was no statistically significant difference in the incidence of the postoperative local venous complications on the injection sites such as thrombosis or phlebitis between both groups.

BACKGROUND: Sevoflurane has been reported to potentiate the effect of rocuronium. We compared the effect of sevoflurane and propofol on intubating conditions and their corresponding hemodynamic changes, and also compared the intubation conditions at different intubation timing using the rocuronium. METHODS: Sixty patients were randomized into four groups: group P (P-60, P-90) received 10 mg/kg/hr of propofol after 2 mg/kg of bolus injection; group S (S-60, S-90) were inhaled with 8 vol% sevoflurane after injection of 50 mg of thiopental sodium. Intubation was attempted at either 60 seconds (P-60, S-60) or 90 seconds (P-90, S-90) after the rocuronium administration. Intubation conditions were assessed and evaluated as excellent, good, poor and inadequate. Single twitch responses were measured at every 30 seconds after rocuronium administration. Blood pressure and heart rate were measured before induction, before intubation and immediately after intubation. RESULTS: Excellent and good intubation conditions were obtained in 60% (n = 9) of group P-60, 73% (n = 11) of group S-60, 92% (n = 14) of group P-90 and 100% (n = 15) of group S-90. Single twitch responses were fewer in group P-90 and S-90 compared to those in group P-60 and S-60 (P < 0.01). Blood pressure and heart rate after intubation were elevated in all four groups. CONCLUSIONS: Intubation conditions were not significantly different between inhalation of sevoflurane and intravenous administration of propofol when using rocuronium. Prolonged interval between rocuronium administration and intubation resulted in improved intubation conditions.

Succinylcholine has been reported to cause elevation of intraocular pressure(IOP.) IOP measurements, following single and mixed intravenous administration of succinylcholine and pancuronium, given immediately after thiopental, were made in 40 surgical patients, to assess the effect of pacuronium on the succinylcholine induced increase in IOP. The major findings of this study were as follows; 1) Tbiopental showed significant lowering effect on IOP. 2) A single intravenous injection of succinylcholine(1mg/kg) caused a slight rise of lOP. 3) A single intravenous injection of pancuronium(4mg) caused a slight decrease of IOP. 4) A mixed intravenous injection of succinylcholine and pancuronium increased the IOP more significantly than succinylcholine alone, This also means that pancuronium do not inhibit succinylcholine induced increase In IOP. 5) Tracheal intubation caused a rise of IOP significantly.

BACKGROUND: Even though propofol having many clinical merits, a vascular pain during intravenous administration of it could maKe us choose other induction agents. One of many METHODS to decrease vascular pain, the use of propofol preserved in a cold temperature (1 4degeesC) was introduced and Known to be effective. The purpose of this study was to compare vascular pain of cold propofol with that of thiopental as induction agents. METHODS: Sixty adult patients for elective surgery were randomly assigned to the two groups according to receiving thiopental (Group I, n = 30) or propofol (Group II, n = 30), then they were divided randomly into two subgroups according to the selection of vascular size; vein on the dorsum of hand or antecubital fossa. As an induction agent, 2.5% thiopental (5 mg/Kg) or cold 1% propofol (2 mg/Kg) were given intravenously during 40 sec. The severity of vascular pain (classified by 4 points verbal category system) and the incidences of pain were compared according to the induction agents and the selection of vascular size. The incidences of moderate to severe pain according to the selection of induction agents were compared. RESULTS: There was no significant difference in the severity, incidence of pain or incidence of moderate to severe pain in both groups, There was no significant difference in the incidence of pain according to the vascular size. CONCLUSIONS: As cold propofol was given slowly (during 40 sec), the vascular pain was not significant to hinder the selection of propofol as an induction agent compared with that of thiopental.

PURPOSE: Recently, the bispectral index monitor has been promoted as an objective measure of sedation depth during pediatric procedural sedation in the emergency department (ED). However, rectal administration of thiopental sodium for pediatric procedural sedation has not been validated. METHODS: Patients aged one to seven years and undergoing primary closure procedures for simple facial and hand laceration in the ED were enrolled. Procedural sedation was performed by rectal administration of thiopental sodium. The bispectral index score and the Ramsay Sedation Scale were recorded every 10 minutes during sedation. The investigator and treating physician were blinded to bispectral index scores, which were later correlated with the Ramsay Sedation Scales values. Receiver operator characteristic (ROC) curves were conducted to determine the ability of the bispectral index score to discriminate various thresholds of sedation depth. RESULTS: One hundred thirty paired measurements were obtained from 12 patients. The Spearman's correlation coefficient for paired measurements, was -0.906 (95% confidence interval: [-9.8] ~ [-8.1], p<0.001). ROC curve analysis demonstrated a high discriminatory power for bi-spectral index scores in predicting the level of sedation, with areas under the curve at least 0.95 for all Ramsay Sedation Scale thresholds. CONCLUSION: Bispectral index monitoring can serve as a useful, objective measure of sedation depth in pediatric procedural sedation with rectal administration of thiopental sodium in the ED.
