Influence of Height and Vertebral Length on Spinal Anesthesia with 0.5% Hyperbaric Bupivacaine / 대한마취과학회지

BACKGROUND: Many factors determine the distribution of local anesthestics in the subaracnoid space. Especially, patient's height is considered an important determinant of the dose of spinal anesthesia. However, the relationship between height and the level of analgesia has not been clearly documented. We studied the correlation between vertebral lengths measured from C7 to the level of the iliac crest (C7-IC), to the sacral hiatus (C7-SH) and to the coccyx (C7-CX) and the level of analgesia injected a fixed amount of local anesthetic in spinal anesthesia. METHODS: Fifty six healthy patients who consented to spinal anesthesia for elective operation were studied. All patient were administered 0.5% hyperbaric bupivacaine 11 mg in the lateral decubitus position on a horizontal operation table. Immediately after drug injection, the patients were turned to the supine horizontal position. For the first 30 minutes, we measured the level of analgesia to pinprick every two minutes. RESULTS: The average of maximum cephalad spread of analgesia was T7.0 1.6. There were weak correlations between patient's height or C7-IC and the level of analgesia. However a significant correlation existed between vertebral length measured from C7 to SH and the level of analgesia. CONCLUSIONS: It is concluded that vertebral length (C7-SH) provides a more meaningful approach to dose selection than height.

Early Detection of Pulmonary Edema by Pulse Oximeter during Cesarean Section: Case report / 대한구급학회지

This case showed that pulse oximeter was helpful for early detection of pulmonary edema during Cesarean section in a parturient woman with preoperative ritodrine treatment. Though arterial oxygen saturation ( Sp02 ) by pulse oximeter was low before the induction of anesthesia, the woman was anesthetized due to emergency situation. SpO2 was continuously low during the operation, so pulmonary edema was suspected. After the operaton, pulmonary edema was diagnosed on the chest x-ray. On the ECG, anteroseptal wall ischemia was detected. Supplementary O2 and diuretics therapy were performed. On the 3rd postoperative day, arterial blood gas analysis was within normal range. Four days after the operation, ECG was normalized and chest x-ray finding was much improved. 10 days later, chest x-ray finding was normalized.

A Statistical Analysis of Postoperative Deaths in the Hospital / 대한구급학회지

Introduction: Anesthesia deaths are rare, while deaths due to surgical or other risk factors are more frequent. The goal of this analysis is to evaluate risk factors associated with postoperative mortality. METHODS: We have analyzed 34,200 surgical patients between 1990 and 1996 through records of anesthesia. The following informations were recorded; age of patients, physical status, site of operation, time of death, primary cause of death. RESULTS: The results are as follows; 1) Of 34,200 surgical patients, 119 died in the hospital. 2) The postoperative mortality rose progressively with age and was highest above 70 years. 3) Within 48 hours, the mortality was 36.1% of total deaths, declined progressively thereafter. The patients who had head operations exceeded 45% of deaths during this period. Eight days after the operation the mortality rate was 34.2% of total deaths and the patients who had an elective operation of the abdomen were 60.8%. 4) 34.2% patients of the total deaths had brain damages. Of these, 79.5% showed physical status V and had an emergency head operation and 47.5% were 50~60 years of age. 17.5% and 13.2% of deaths were due to sepsis and respiratory insufficiency and 48.6% of these two categories were physical status II, III and had an elective operation and 55.5% were above 60 years. CONCLUSION: The postoperative mortality was highest in the patients who had an emergency head operation and primary cause of death was brain damage. The patients of above 60 years, had a physical status II, III, had an elective abdominal operation were succeptable to sepsis and respiratory insufficieny.

Effects of Augmented Minute Ventilation on Cardiovascular and Ventilatory Changes during the Laparoscopic Cholecystectomy under General Anesthesia / 대한마취과학회지

BACKGROUND: The pneumoperitoneum created by CO2 insufflation during laparoscopic cholecystectomy has several potential hemodynamic and respiratory consequences. The purpose of this study is to investigate the effects of augmented minute ventilation on cardiovascular and ventilatory changes and to prevent hypercarbia due to CO2 insufflation during laparoscopic cholecystectomy. METHODS: Thirty-six patients were divided into three groups according to the level of minute ventilation. The three groups were: control group C (minute ventilation 100 ml/kg, respiratory rate 12 per minute), group R (MV 150 ml/kg, RR is 18 per minute) and group V (MV 150 ml/kg, tidal volume is 1.5 times as much as group C). We repeatedly measured mean arterial pressure , pulse rate , arterial blood gas analysis and end tidal carbon dioxide and peak inspiratory airway pressure before CO2 insufflation, 15 and 30 minutes after CO2 insufflation and 15 minutes after CO2 deflation. RESULTS: During CO2 insufflation, MAP significantly increased but PR showed little changes in all three groups. PaCO2 and PetCO2 increased in group C, whereas in group R and V, they remained unchanged during CO2 insufflation. But the level of PaCO2 in group V decreased more than in the other two groups after CO2 deflation,. PIP in group V increased 3 times as much as the control value. CONCLUSIONS: These results suggest that augmented minute ventilation in group R and V, prevented hypercarbia during CO2 insufflation and increasing the tidal volume in controlled ventilation was more effective than increasing respiratory rate after CO2 deflation.

A Case of Hypoxic Encephalopathy Following Anesthesia for a Patient with Ludwig`s Angina / 대한마취과학회지

Ludwig's Angina is the term given to the symptoms resulting from infection of the submandibular space and is characterized especially by extreme edema of the floor of the mouth. Airway obstruction and respiratory difficulty is common due to edema of the mouth, tongue, and the glottis, from mediastinitis due to spread, or from septicemia or pneumonia. Thus it is necessary for the anesthetist to attend to specific management of airway maintenance. A 49 year old male had an operation for incision and drainage under balanced anesthesia. After the operation, posthypoxic myoclonus due to anoxia for three minutes appeared while in the recovery room. The patient, controlled by oxygen supply and diazepam and antiepileptics, has recovered from the seizures, but has not recovered from intention myoclonus and speech disturbance, which are slowly improving. This report describes this case of posthypoxic myoclonus following anesthesia and reviews the literatures.

The Effect of Regional Sympathetic Block in the Treatment of Herpes Zoster / 대한마취과학회지

We must be assured that sympathetic ganglion block interrupts a vicious cycle of nerve impulses. Therefore, it prevents vasospasm and improves local circulation. The sympathetic ganglion block is effective in acute stage of herpes zoster and reduces the incidence of post-herpetic neuralgia. Herpes zoster is more often involved in an immunosuppressive imbalance. Three cases of herpes zoster were treated by repeated sympathetic ganglion block with 1% proved. Duration from onset of pain was 1 week, 1 month and 2 months, respectively. The block decreased the degree of pain markedly and dried up the vesicle in the early stage. Two of these three cases had suffering from diabetes melitus.

A Case of Status Asthmaticus during Spinal Anesthesia for Cerarian Section of Chronic Asthma Patient / 대한마취과학회지

Asthma involves intermittent episodes of bronchospasm associated with wheezing and dyspnes and asymptomatic period. Many drugs and anesthetic agents can affect bronchomotor tone and asthmatic patients requiring anesthesia are at higher risk than nonasthmatics. The anesthetic management of the asthmatic patient continues to present a challenge to the clinical anesthesiologis, despite increased knowledge and better understanding of the pathogenesis of bronchial asthma and the availability of safer and more effective anesthetic agents and methods. We have experienced status asthmaticus during spinal anesthesia for Cesarian section of a chronic asthma patient. We report the case and review the relevant literature.

Residual Epidual and Subural Hematoma in the Occipital Area / 대한마취과학회지

In a 8 year-old boy who had epidural hematoma in the occipital area, had an episode of dislodgement of the endotracheal tube due to improper position. After operation, there were drowsy consciousness, irregular respiration, apnea, absence of cough reflex and swallowing reflex. Then these was no improvement in spite of treatment, and because of this hypoxic encephalopathy was diagnosed. WE suspected there might be some pathologic lesion volving the respiratory center and lower cranial nerves. CT scanning was performed and the result was diagnosed with epidural hematoma and subdural hematoma in the posterior fossa. The patient was reoperated.

A Case Report of Asthmatic Breathing with Lidocaine / 대한마취과학회지

Lidocaine is considered a safe and effective local anesthetic in anesthesiology and is the standard to which new amide anesthetics are compared. As it an amide derivative, and the frequency with which lidocaine elicits an allergic response is much less than that of anesthetics derived from paraaminobenroic acid esters. Case reports od sensitivity to lidoeaine have been reported, but they are rare. This 29 year old male patient had on episode of asthmatic breathing after supraclavicular brachial plexus block using 30 ml of 1% lidocaine with epinephrine(1:200,000). We report a case of asthmatic breathing due to lidocaine and a review of the literature for allergy local anesthetics.

Anesthetic Management for the Palient with Insuliaoma / 대한마취과학회지

Hyperinsullinism and the resultant hypoglycemia are hallmarks of functioning beta islet cell tumors of the pancreas. The management of one case of insulinoma during surgery for the removal of the tumor is described and the available literature on the subject reviewed. The outline of the anesthetic management for the insulinoma is as follows: 1) Anesthetists should understand the signs and the symptoms of hypoglycemia and hyperglycemia. 2) Preoprative management: a) infusion of glucose for avoiding hypoglycemia due to NPO after midnight. b) glucocorticosteroid administration with premedications. 3) Operative management: a) continuous determination of blood glucose level may be helpful. b) Maintenance of the glucose level about 50mg% above symptomatic CNS level have the advantage that exicision of the infulinoma can be immediately judged. c) The use of an agent that decreases CMRO2 and does not affect the insulin-glucose ratio is rational choice when concern about hypoglycemia exists. Thiopental-enflurane anesthesia with controlled ventilation maintaining normocarbia is recommended. d) beta-adrenergic blocker. These drugs must be avoided in the hypoglycemic state.

Anesthesia for an Insulinoma Case / 대한마취과학회지

Hyperinsulinism caused by a functioning islet cell tumor of the pancreas is an uncommon but well established metabolic entity which can usually be diagnosed accurately. We treated a patient with functioning insulinoma recently. The outline of the particular management given for the course of the anesthesia of the patient was as follows: 1) Control of blood glucose a) pre- and intraoperative hypoglycemia; Glucose was administered through intravenous drip or orally. b) postoperative transient hyperglycemia; Insulin was administered if necessary and a small amount of glucose uptake, occurred. 2) Anesthetics, and supplemental drugs Drugs with no or little effect in increasing blood glucose were used. 3) Beta-adrenergic blockers These drugs were not used in the hypoglycemic state because of potentiating insulin activity.

A Case of Acute Massive Pulmonary Collapse following Induction of Anesthesia / 대한마취과학회지

This report concerns a child who developed left ; Iung collapse during induction of anesthesia for suture ligation of patent ductus arteriosus. Acute massive collapse of a lobe, a whole lung or even both lungs in the space of a few minutes without apparent cause is said to be a rare elinical entity. Clinically this condition is manifested by difficulty in breathing or in inflation of the lung. On auscultation, there may be rhonchi or no sound of any air entry into the lung. If unrelieved, this condition will progress, with hypoxia and cardiac arrest. " We observed that the affected lung expanded during inflation with very high pressure ventilation, and then the collapsed lung was smoothly inflated after suture ligation of patent ductua arteriosus without any specific management. It appears that the development of lung collapse is not through the wrong choice of agents or technics of anesthesia, but from failure to appreciate the hemodynamics of ductus arteriosus or unknown factors. We could not find a definite mechanism of lung collapse, but there are contributing factors including compression of a main brobchus, bronchial secretion, decrease of surfactant and others. The operation was successful and she recovered satisfactorily.
