BACKGROUND: Epidural steroids injections are often used for the treatment of low back pain but their effects on the endocrine system have not been determined. Few studies have quantified the degree or duration of the suppression of the hypothalamic-pituitary-adrenal (HPA) axis in humans given epidural triamcinolone injection (ETI) for low back pain. The evaluation of the blood adrenocorticotropic hormone (ACTH) and cortisol was undertaken to determine the extent of suppression of the HPA axis in patients given ETI. METHODS: Lumbar epidural triamcinolone injections were performed on the painful lumbar intervertebral space with patients in the lateral decubitus position. The injection consisted of 40 mg of triamcinolone acetonide diluted in 10 mL of 1% lidocaine. Patients remained in the lateral position for 10 min after the procedure. Basal blood sampling was performed at 30 min before ETI and tested blood sampling was obtained at 7 days, 10 days, and 14 days after ETI. RESULTS: The blood cortisol level was significantly decreased at 7 days and 10 days but at 14 days was not significantly decreased and the blood ACTH level was not significantly decreased at 7 days, 10 days, and 14 days. CONCLUSIONS: Above results demonstrate that blood ACTH and cortisol level normalize 7 days and 14 days, respectively, after epidural triamcinolone 40 mg injection.

BACKGROUND: Epidural morphine has side effects, especially pruritus, nausea, and vomiting. Butorphanol has been added in studies to reduce these side effects in post cesarean patients. The purpose of this study was to evaluate the side effects and analgesic efficacy when a combination of epidural morphine and butorphanol was administered in patients having combined local anesthetic and opioid epidural infusion. METHODS: Sixty patients having epidural anesthesia for cesarean section were randomly divided into two groups. Group M (n=30) received a bolus of 0.25% bupivacaine 4 ml, morphine 2 mg, and saline 0.75 ml, whereas group B (n=30) received a bolus of 0.25% bupivacaine 4 ml, morphine 2 mg, and butorphanol 1.5 mg (0.75 ml). Continuous epidural infusion was done by Two-day Infusor containing either 0.25% bupivacaine 75 ml, morphine 5 mg, and saline 20 ml in group M or 0.25% bupivacaine 75 ml, morphine 5 mg, butorphanol 4 mg (2 ml), and saline 18 ml in group B. We compared the side effect and analgesic effect of group M to those of group B for 2 days. RESULTS: The incidence of pruritus and vomiting were reduced significantly in group B (p<0.05). There were no significant differences between both groups in the incidence of nausea or other side effects as well as no differences in analgesic effect. CONCLUSIONS: We conclude that the addition of butorphanol to morphine in combined local anesthetic and opioid epidural infusion for postoperative analgesia decreases the occurrence of pruritus and vomiting without significant increase of other side effects and adverse effect on analgesia.

BACKGROUND: Measurement of echocardiographic mitral valve area (MVA) is an useful noninvasive method of estimating the stenotic mitral valve area. This study was undertaken to evaluate the accuracy of echocardiographic MVA measurement by comparing MVAs measured by the planimetric and pressure half-time method versus direct MVA measurement by using a cone shaped device specifically made for direct measurement of MVA. METHODS AND RESULTS: The study population consisted of 22 consecutive patients from August 1993 to February 1996. All the patients underwent 2D planimetry and Doppler echocardiographic MVA measurement before and after valve replacement surgery ; direct measurement also was performed after surgery. Five patients (22.7%) had normal sinus rhythm, and the rest of the patients had atrial fibrillation. Two-dimensional echocardiographic examinations were attempted in 22 patients, and adequate measurements were obtained in 21 of the patients studied. Mean mitral valve area were 0.99+/-0.32cm (2) ranged from 0.42 to 1.68cm (2) on 2D planimetry method, 0.93+/-0.32cm (2) ranged from 0.42 to 1.68cm (2) on Doppler pressure half-time method, 1.17+/-0.20cm (2) ranged from 0.93 to1.68cm (2) on direct measurement of mitral valve area after surgery. 2D planimetry method (r=0.621, p=0.003, SE=0.165), pressure half-time method (r=0.454, p=0.003, SE=0.187), and transmitral peak velocity (r=-0.480, p=0.026, SE=0.189) was relatively well correlate with operative mitral valve area. There was relatively good agreement between direct and 2D planimetric measurement and between direct and Dopler pressure-half time method. CONCLUSION: 2D planimetry and Doppler pressure half-time method on echocardiography are useful, noninvasive measurement method in patients with mitral stenosis.
