BACKGROUND: Mivacurium has a characteristics of rapid onset and the shortest duration of non- depolarizing neuromuscular relaxants and the onset of action could be accelerate more rapidly by using priming principle. The purpose of this study was to compare the onset time of mivacurium by priming principle with succinylcholine during rapid endotracheal intubation. METHODS: 36 patients were randomly divided into 3 groups: mivacurium group by priming principle (Group 1), mivacurium group by bolus injection (Group 2) and succinylcholine group (Group 3). In Group 1, subparalyzing dose of 0.02 mg/kg was administered 2 minutes before principle dose of 0.25 mg/kg was given. Onset time and intubating conditions were observed when twitch tension was reduced by 25% block in each group. RESULTS: The onset of Group 1 (75 sec) was significantly faster than that of Group 2 (90 sec) (p<0.05) but was significantly slower than that of Group 3 (37.5 sec) (p<0.05). Intubating conditions were excellent in all groups. CONCLUSIONS: The attempts of priming principle with mivacurium could accelerate the onset of action of mivacurium compared with that of bolus injection but their onsets were shorter than those produced by succinylcholine.

BACKGROUND: The implementation of intraoperative normovolemic hemodilution is a strategy used in an attempt to diminish the need for or obviate allogeneic transfusion and to avert the potential complications. The goal of this study was to evaluate the safety and efficacy of moderate intraoperative normovolemic hemodilution. METHODS: Fifteen patients scheduled for posterolateral spinal fusion underwent intraoperative normovolemic hemodilution with 10% pentastarch to a target hematocrit level of 25% (hemodilution group). All units of blood procured by hemodilution and additional allogeneic blood was transfused in the perioperative period to maintain the hematocrit level of>25%. We investigated the effect of hemodilution on whole blood coagulation as measured by the thromboelastography and, evaluated its efficacy of decreasing the need for allogeneic blood transfusion as compared to the nonhemodilution group, retrospectively. RESULTS: Hemodilution with pentastarch caused a decrease in response and coagulation time (p<0.01) but did not influence on the alpha angle and maximum amplitude on thromboelstogram. Amount of transfusion of allogeneic blood was 4.1 1.7 units for the hemodilution group and 5.0 1.5 units for the nonhemodilution group. Net red blood cell volume ""saved"" from hemodilution was about 120 ml. CONCLUSION: Moderate intraoperative normovolemic hemodilution with pentastarch does not affect the coagulability of whole blood. But its efficacy of decreasing the need for allogeneic blood transfusion is minimal.

Journal of Korean Medical Science 1993;8(4):290-292
A case of difficult intubation is described in which the problem was overcome by use of the laryngeal mask airway (LMA). The patient had difficulty in mouth opening due to severe burn scar contracture around the mouth and limited access prevented tracheal intubation. The use of LMA is shown to have obviated the need for tracheal intubation in the case of a patient whose injuries would have made this technique difficult.

BACKGROUND: Phantom limb sensation is an unusual position sense of the extremity during nerve block that the position of extremity is misinterpreted as being flexed, or elevated, when actually they are in neutral position. Whether it is from the fixation of proprioceptive input at the time of motor blockade or from unmasking of the pattern which has been already present in the CNS is still controversial. We perfomed this study under the assumption that phantom limb sensation can still be reproduced without the influence of position at the time of nerve blockade. METHODS: Thirty-six patients scheduled for elective orthopedic surgery were randomly assigned. For 26 patients, spinal anesthesia was performed with hyperbaric 0.5% tetracaine or bupivacaine at lateral decubitus position and the position was changed to supine immediately. Existence of phantom limb sensation and the level of anesthesia was recorded at 10 and 20 minutes after injection of local anesthetics. For 10 patients, same local anesthetics were injected after patient's legs were straightened in lateral decubitus position. RESULTS: Forteen out of 26 patients whose position were changed to supine immediately after the injection of local anesthetics experienced phantom limb sensations. Five out of 10 patients whose legs were kept straight before the injection of local anesthetics experienced phantom limb sensations. Previous history of trauma was positively related to the expression of phantom limb sensation. CONCLUSION: Our data showed that the expression of phantom limb sensation is reproducible. And this was not related to the position at the time of spinal anesthesia. Trauma seems to be an important factor related to the expression of phantom limb sensation.

We performed trans scleral fixation techniques for implantation of posterior chamber lens in 25 eyes, in case of incomplete zonular or capsular support. This was done by securing both haptics of the posterior chamber lens to the sclera at the ciliary sulcus with 10-Onylon suture. Postoperative follow-up time ranged from 12 to 23 months, with all patients having at least one year of follow up. At the last follow up visit, 16 eyes (72%) had a vision of 20/50 or better, and 13 eyes (52%) had a vision of 20/30 or better. The transscleral fixation related complications included retinal detatchment, glaucoma and cystoid macular edema. During the relatively longterm follow up period, we did not find any serious complications due to the intraocular lens and there was no significant postoperative changes in the visual acuities.

BACKGROUND: The laryngeal mask airway (LMA) has many advantages including easy insertion, less trauma, minimal cardiovascular changes. And the elderly have many problems such as poor dentition, limited cervical extension and age related cardiovascular changes, so endotracheal intubation in geriatric patient is sometimes difficult and harzardous. This clinical study was designed to investigate availability and problems of LMA insertion in geriatric patients. METHODS: 60 geriatric patients undergoing elective surgery were induced with intravenous injection of pentothal sodium or propofol, vecuronium or atracurium and inhalation of O2, N2O, enflurane or isoflurane. After deep anethesia and full muscle relaxation LMA was inserted and cuff was inflated. When blind insertion was failed, laryngoscope was used. Anesthesia was maintained with inhalation of O2, N2O, enflurane or isoflurane under positive pressure ventilation. Thereafter, we observed peak inspiratory pressure and any incident including gas leakage, stomach distension, regurgitation of stomach content intraoperatively and then any complication postoperatively. RESULTS: LMA placement was successful in 98.8%, but LMA insertion in geriatric patient had some difficulty because patient's tongue slided down with LMA due to oropharyngeal dryness, teeth loss. Intraoperatively LMA was well maintained under positive pressure ventilation. There was no critical incident associated with LMA use. CONCLUSIONS: LMA is safe and may have a useful role in the anesthetic management of geriatric patients who have many problems such as poor dentition, limited cervical extension and age related cardiovascular changes.

BACKGROUND: Caudal block has proved to be a satisfactory method of providing perioperative analgesia for pediatric surgery in inguinal and perineal areas. This study was designed to evaluate the effects of ketamine or clonidine as an adjunctive of caudal block produced by bupivacaine. METHODS: One hundred ninety five children aged 1~10 years, undergoing surgery in inguinal and perineal areas as ambulatory cases, were randomly allocated to one of four groups after the induction of general anesthesia; 0.25 % bupivacaine 1 ml/kg(group B), 0.25 % bupivacaine 1 ml/kg with ketamine 0.5 mg/kg(group K), 0.25 % bupivacaine 1 ml/kg with clonidine 1 microgram/kg(group C), and local infiltration group(group L). Postoperative pain was assessed using an objective pain scale and the incidence of side effects, such as urinary retention and nausea/vomiting was observed after surgery. RESULTS: In the group B and L, OPS score was higher and analgesics were more frequently administered than group K and C at the recovery room and at home after discharge(p<0.05). There was no difference between the groups in the incidence of nausea and vomiting but urinary retention at the recovery room was more frequent in group C than other groups(p<0.05). CONCLUSIONS: Caudal block provided more effective postoperative analgesia than local infiltration. In caudal block, the addition of ketamine or clonidine prolongs the duration of postoperative analgesia without significant increase in side effects.
