A Clinical Study of Splanchnic Nerve Block / 대한마취과학회지

BACKGROUND: It is difficult to manage intractable pain from advanced carcinoma of the upper abdomen. One method used to control pain associated with these malignancies is to block the splanchnic nerve. We investigated that VAS (visual analogue scale) difference before and after splanchnic nerve block (SNB) and pain relief day. Also we studied relationship between VAS before SNB and pain relief day. METHODS: A rewiew of 70 patients who took splanchnic nerve block (SNB) from September 1994 to February 1998 was carried out to assess age, sex, primary diseases, pain sites, VAS before and after SNB, date of diagnosis, date of SNB, date of death and pain relief day, etc. RESULTS: Of 70 patients, 44 were males and the remaining 26 were females. The causes of pain were stomach cancer 28 (40%), pancreatic cancer 18 (25%), gall bladder cancer 7 (10%), hepatoma 6 (8.6%) respcectively. Average day from diagnosis to SNB was 272 and average day from diagnosis to death was 341. So, patients died on the average 69 days after they took the splanchnic nerve block in pain clinic. VAS average before SNB was 8.01 and VAS average after SNB was 3.64. Patients felt pain relief during 35 days after SNB. Pain relief day of patients who had lower VAS before SNB was longer than that of patients who had higher VAS before SNB. CONCLUSION: Early application of splanchnic nerve block will make the patients endure the cancer pain more easily.

Continuous Blood Pressure Monitorings during Cardiovascular Opertions in Takayasu`s Syndrome / 대한마취과학회지

We had examined the invasive blood pressure monitoring of superficial temporal, radial and femoral artery in two eases of Takayasus syndrome with mitral regurgitation and acute renal artery infarction. Mitral valve replacement and aorto-renal bypass graft were done by using cardiopulmonary bypass and one-lung ventilation respectively, The results are ; 1) Superficial temporal artery monitoring was more reliable and less fluctuant than femoral and radial artery monitoring in blood pressure. But we dont know the relationship of adequate cerebral perfusion pressure and superficial temporal artery pressure. 2) The femoral artery pressure monitoring was not adequate when the patients had a problem with ascending and descending aorta patency. 3) We had good results in the patient management by the monitoring of superficial temporal artery pressure.

Epidural morphine on ventilatory function in chest trauma and thoracotomy patients

Epidural morphine injection was done in nineteen patients who had been admitted from March to August 1990 to the Intensive Care Unit, Severance Hospital, Yonsei Medical Center for respiratory care including ventilator care. Morphine suplphate, 2.67 +/- 0.27 mg was injected one to three times to four patients after chest trauma, and to fifteen patients after thoracotomy. Tidal volume and vital capacity were increased from 4.45 +/- 0.48 and 8.31 +/- 0.50 to 6.91 +/- 0.41 and 12.81 +/- 0.73 mg/kg. However, respiratory rates decreased from 26.07 +/- 1.41 to 20.07 +/- 1.16/min. Inspiratory force increased from -13.40 +/- 1.31 to -26.53 +/- 1.82 cmH2O. Pain score decreased from 9.22 +/- 0.57 to 3.56 +/- 0.83 during this period. PaCO2 did not differ significantly (39.33 +/- 1.13 and 39.48 +/- 1.42 mmHg). Side effects such as pruritis and urinary retention were treated with naloxone 7 approximately 10 ng/kg/min. Mean arterial pressure and pulse rates stayed stable during the study periods. Ventilator hours and ICU stays differed from the control group. However, the duration was not statistically significant. The control group consisted of patients who were admitted during the six months from September 1989 to February 1990 to the ICU for respiratory care, without epidural morphine injection.

Changes in Levels of Epinephrine and Norepinephrine before during and after Cardiopulmonary Bypass / 대한마취과학회지

It is believed that catecholamine secretion is increased during cardiopulmonary bypass. However, the periods of maximum increase in catecholamine levels during cardiopulmonary bypass are different among several authors. 15 patients having valvular surgery were studied. Plasma epinephrine and norepine- phrine were determined by high performance liquid chromatography at 8 stages of the operation. During bypass plasma catecholamine levels continued to rise and maximally increased until aortic cross clamp off, and decreased gradually. Norepinephrine also showed the same results initially, but then increased gradually after the end of bypass. During bypass the maximum increases in epinephrine and norepinephrine were sixfold and twofold respectively in comparison with the levels prior to induction, which suggests that the predominant humoral response to cardiopulmonary bypass appears to be adrenomedullary release of epinephrine. The catecholamine levels at the period of aortic cross clamp off was higher than that of the lowest body temperature. There was no correlation between the increases in catecholamines and mean arterial pressure. Temperautures and eatecholamines also showed no correlations.

Clinical experiences of fiberoptic bronchoscopy in patients with respiratory failure in the intensive care unit

Seventy-nine fiberoptic bronchoscopies were performed in 46 Patients during 2 years in the Intensive Care Unit of Severance Hospital, Yonsei Medical Center. Bronchoscopies were done more than twice in 13 patients. Forty-three bronchoscopies were done through the orotracheal tube in 27 patients, and narcotics and sedatives such as morphine sulfate, diazepam and lorazepam were added with pancuronium bromide during 52 bronchoscopy procedures in 21 patients. Ventilatory support was accomplished by control mode ventilation for 63 bronchoscopies in 37 patients. Twenty-four patients were from the surgical department, and 37 bronchoscopies were performed in 18 patients in a post-thoracotomy state. Twenty-two patients were nonsurgical patients. We performed 48 bronchoscopies in 26 patients to treat lung haziness, 14 bronchoscopies in 3 patients to confirm the operative anastomosis after pneumonectomy or tracheoplasty, and 11 bronchoscopies to confirm the airway patency and vocal cord movement. We obtained good results from 41 bronchoscopies performed for therapeutic purposes and 28 bronchoscopies done for diagnostic purposes. But in 4 patients with pleural effusion and pneumonia, we could not get any improvement in chest X-ray taken after bronchoscopy. We suggested other procedures in 6 patients for diagnosis or treatment, such as suspension laryngoscopy, thoracentesis, ultrasonogram and laser surgery.

Chimical Lumbar Sympathectomy - Five cases report - / 대한마취과학회지

Pain is a sensory experience that is subjective and individual. It frequently exceeds its protective function and becomes destructive. We have met one case of causalgia, three cases of Buergers disease, and one case of arteriosclerosis obliterance. They sufferred from persistent pain and exkausted with the marked distrophy of affected limbs. Management of these patient involving lower limbs is a continuing challenge. Many other therapheutic procedures could be tried for these patients, but we tried chemical lumbar sympathectomy for these cases. With respect to the lower extremity, four patients had neurolysis of the 1st, 2nd and 3rd ipsilateral or 2nd and 3rd bilateral lumbar ganglia using 3 to 5 ml pure alcohol for each space under the image intensifier. Immediately after these procedure, rest pain has relieved dramatically in most cases and marked skin temperature rising. This implied increased peripheral blood flow of sympathectomised portion and the relief of rest pain is probably explained by destrcution of the afferent pain fibres running with the sympathetic trunk.

Respiratory Parameters of Pressure Support Ventilation and Synchronized Intermittent Mandatory Ventilation during the Weaning Process / 대한마취과학회지

SIMV (synchronized intermittent mandatory ventilation) is a volume assisted mode which a patient inspiratory demand results in a clinician-controlled tidal volume and flow rate. However, PSV (pressure support ventilation) has the ability to augment spontaneous breaths with a variable amount of inspiratory positive pressure with a clinician-selected level of inspiratory airway pressure. To compare the effects of SIMV and PSV on respiratory function, experiments were performed on 12 stable patients during the weaning process and tidal volume, airway pressure, arterial blood gas tensions, blood pressure, and heart rates were measured during SIMV, and after 2 mins after removal of mechanical ventilation support. The same measurement as SIMV (except mandatory respiratory rates) were performed during PSV. The PSV level was reduced in the 5 cm2O step every 10-15 mins. The results of respiratory parameters and hemodynamic data showed that tidal volume, blood pressure, heart rates, and arterial blood gas tensions were similar, but there were significantly lower ventilatory rates, lower peak airway pressure and lower mean airway pressure during PSVmax than SlMV, and PSV resulted in improved patient comfort. It was concluded that PSV could be used to unload the patients ventilatory muscles and provide an appropriate level of mechanical ventilation support similar to SIMV weaning approaches.

Effect of Extreme Leukocytosis on Arterial Oxygen Tension / 대한마취과학회지

Arterial blood gas analysis has become an integral part of the clinical evaluation of the patient with known or suspected pulmonary disease. However, when the results of the measurements show arterial hypoxemia which is out of proportion to the clinical and X-ray evidence of lung disease, we may consider potential errors in measurement involving the blood gas analyzer or methods of blood sample storage. We experienced spurious hypoxemia in a patient with extreme leukocytosis (220.0 X 10(3)/mm3) secondary to leukemia. The degree of PaO2 decay was blunted by placing the blood on ice.

High Frequency Jet Ventilation in Tracheal Tumor Surgery / 대한마취과학회지

A 38-year old male patient underwent tracheal reconstruction because of a tracheal tumor. A CT scan showed that the mass was located 5 cm above the carina, the size was 2x1.5cm, and there was a 50% narrowing of the stenotic segment. After endotracheal intubation (1.D. 8mm), a pediatric suction catheter (lenght:40cm, diameter: 2mm) was inserted with a stylet at the side of the tube to pass the stenotic segment with fiberoptic bronchoscopic guidance. Conventional ventilation with an inhalation agent was performed and HFJV was started just prior to the tracheal incision. A driving gas pressure of 1 kg/cm, respiratory rate of 120/min., I:E ratio fo 1:1, and Fio2 of 1.0 were applied through the suction catheter. Ten minutes after HFJV, PaCO2showed 50mmHg. Hypercabia was relieved by increasing the driving gas pressure from 1kg/cm(2) to 1.5 kg/cm(2). HFJV was performed for one and a half hours. During the procedure, blood gas analyses were perfomed frequently and all results revealed an adequate ventilatory status. After completing the end to end anastomosis, conventional ventilation was started until surgery was ended. The patient's course proceeded uneventfully and he was discharged 13 days after surgery.

Roentgenographic Confirmation of Central Venous Catheter Tips through the External and Internal Jugular Veins in Children / 대한마취과학회지

Catheterization of the innominate vein or superior vena cava vein via the external and internal jugular veins was attempted in 68 pediatric patients weighing less than 20 kg in body weight who were scheduled for cardiovascular and pulmonary surgery. Both jugular veins were utilized in 63 cases, of these, and post operative X-ray confirmed a 19% malposition rate. Catheterization was performed in 45 cases throuhg the left external jugular veins and in 18 cases through the right external jugular vein,and the malposition rates were 25% and 6% respectively. The right internal jugular vein, utilized in 5 cases and, all provided successful results. Difficulty was encountered in passing of the catheter in 32% of the cases using both external jugular veins. Catheter curling was noted in 1 cases. No complications were encountered during and after catheterization.

Pulse oximetry during shunt surgery in pediatric patients with tetralogy of fallot

Pulse oximetry is a noninvasive technique for measuring O2 saturation (SpO2) continuously. We applied pulse oximetry to 9 pediatric patients with tetralogy of Fallot during shunt surgery. Arterial oxygen tensions (PaO2) and saturations (SaO2) were also measured at the time of postinduction, just before the shunt, after the shunt and at the end of the operation. The SpO2 and SaO2 levels were identically changed in all 4 periods. The PaO2 was increased a little without statistical significance after the shunt procedure and at the end of the operation compared with the values before the shunt. However, SaO2 values increased with statistical significance after the shunt procedure and SpO2 values also showed similar increases with significance. In conclusion, continuous monitoring of SpO2 by pulse oximetry, instead of PaO2, is a very useful and reliable method to assess the improvement of perfusion after shunt, particularly in cyanotic cases.

Application of HFJV in Tracheal Stenosis / 대한마취과학회지

Due to the increased use of tracheostomy and intermittent positive pressure ventilation, patients with trscheal stenosis have become more frequent. Recently we experienced a patient with tracheal stenosis who was tracheostomized upon admission, but unfortunately the stenotic lesion was located below the end of the tracheostomy tube. The stenotic lesion was l.6cm above the carina, its diameter was 0.5 cm, and the length of the stenotic segment was about 2cm, A3,5 mm(I.D.) endotracheal tube was passed through the stenotic lesion via the tracheostomy site, and high frequency jet ventilation was applied with a swivel connector. Immediately after the start of surgery, CO2retention occurred and the driving gas pressure increased from 4p to 5p psi, the I:E ratio from 1:2 to 1: 3, but the respiration rate (100 bpm) was maintained as before. CO2retention was relieved soon. Following end to end anastomosis a 6. 0 mm(I.D.) cuffed endotracheal tube was intubated orally and inhalation anesthesia using N2O-O2-Halothane was maintained until the surgery was completed.

Application of Selective Nondependent Lung CPAP during Surgery for Bronchiectasis / 대한마취과학회지

One lung ventilation with a double lumen endobronchial tube during thoracic anesthesia is necessary for the protection of the healthy lung from contamination by the diseased lung and offers acceptable conditions for the surgeon. During one lung ventilation hypoxemia can frequently occur even with the administration of 100% oxyge. Recently we experienced markedly improved oxygenation during one lung anesthesia with a right sided double lumen endobronchial tube with application of CPAP 10cmH2O in the nondependent lung in a left lower lung brochiectatic patient. The healthy dependent right lung was ventilated by a conventional mechanical ventilator with FiO2 1.0, tidal volume 10ml/kg and respiration rate 12/min. Anesthesia was maintained with O2-halothane. Fifteen minutes after two lung ventilation in the right lateral decubitus position, the PaO2 and PACO2 were 400 and 33 torr respectively. 15 minutes after one lung ventilation PaO2 decreased to 99 torr. 15 minutes following application of CPAP 10cmH2O, the PaO2 increased to 229 torr, 30 minutes after CPAP 331 torr, and 2 hours after CPAP it rose to 373 torr. The nondependent lung was motionless and slightly expanded, and the surgical field was suitable for surgery.
