Background: Post-dural puncture headache (PDPH) is one of the well-known complication of spinal anesthesia. Epidural blood patch is the treatment of choice for PDPH but is rarely used for the prevention of PDPH after spinal anesthesia. The purpose of this study is to observe the effectiveness of epidural blood patch for prevention of PDPH and to evaluate the complications after epidural blood injection. Methods: Three hundred patients (ASA I or II) receiving spinal anesthesia were studied. They were randomly devided into two groups. Patients in Group I, the control group, were maintained in a supine position for 24 hour after spinal anesthesia. Patients in Group II, the study group, received 3 ml of autologous blood in the epidural space after spinal anesthesia. PDPH was evaluated for 5 days. The incidence, location, onset, and duration of headache in the patients presenting with PDPH were measured for 5 days, and the complications following epidural blood patch in Group II were observed for 2 weeks. Results: The incidence of PDPH in group I was 11%, but 0% in group II. There were no specific complications following epidural blood patch in Group II. Conclusions: This study suggest that the 3 ml epidural autologous blood patch is an useful method for the prevention of PDPH in patients with spinal anesthesia.

Pain relief becomes a major concern when treating patients with rib fractures so adequate ventilation must be maintained. Many techniques have been described for the management of frectured ribs, including systemic analgesics, intercostal nerve blockade, intrathecal morphine, epidural bupivacaine and epidural morphine. This case report illustrates the successful use of epidural narcotics in a patient with multiple fractured ribs.

The popular term malignant hyperthermia syndrome (MHS) refers to a clinical syndrome classically observed during general anesthesia. It is characterized by a rapidly increasing .temperature and a high mortality rate. A case of MHS was experienced which developed 60 minutes after induction of general anesthesia with thiopental sodium, succinylcholine, halothane, N2O and 02. High fever, muscle rigidity and cyanosis developed and were followed by arrythmia and unstable blood pressure. Anesthesia was terminated and vigorous emergency treatment was attempted. The patient died about 6 hours after induction of anesthesia.

The usefulness of nondepolarizing muscle relaxants for intubation is limited by a relatively slow onset of neuromuscular block compared to that achived with succinylcholine. But, authors have reported that larger doses of nondepolarizing muscle relaxants produce a more rapid onset of maximal neuromuscular block and conditions conductive to endotracheal intubation and recent reports support the use of the "priming principle in the clinical practice of anesthesiology. This phenomenon may apply to all nondepolarizing relaxants: it is reported to facilitated neuromuscular blockade and tracheal intubation when used with atracurium, vecurouium, alcuronium or pancuronium. In this study, administering a small subclinical dose of atracurium (75ug/kg) Smin. prior to the remainder of an intubating doae of atracurium (250ug/kg) had no different on grade of block for intubation compared to single IV bolus of atracurium (500ug/kg).

Evaluation of hemodynamics in venous malformation (VM) in the head and neck area is done by direct puncture venography before alcohol sclerotherapy, but it is difficult due to a variable degree of filling in from the artery and filling out into the draining vein. We present our preliminary experience of 4D MRI to evaluate VM hemodynamics. Four patients with venous malformation in the maxillofacial area underwent both 4D MRI and direct puncture venography before alcohol sclerotherapy. To find out appropriate velocity encoding (VENC) for VM, we applied 5-50 cm/sec VENC. Significant high-flow foci demonstrated by phase changes in magnitude images were compared with lesion types shown on a direct puncture venogram. Detection of flow in VM was possible in magnitude images or phase-difference images when VENC was set to less than 30 cm/sec. Appropriate VENC for VM was regarded as less than 5 cm/sec. High-flow areas in the dilated venous sac demonstrated focal spots or linear band-like areas on phase changes of 4D MRI. Appropriate VENC application was mandatory to detect flow in VM. Flow information on 4D MRI provided flow information in VM which was not detected on a direct puncture venogram in the compartmentalized lesion and thus can make alcohol sclerotherapy safer.

Purpose: To determine the incidence and the time to failure of repaired short external rotator muscles through aposterolateral approach in total hip arthroplasties; and to describe the correlation between failure of the repaired short external rotator muscles and the hip dislocation rate. Materials and Methods: Between January 2003 and October 2003, 51 patients (55 cases) were treated with primary, uncemented total hip arthroplasties. The average patient`s age was 51 years (33 men, 19 women). After the short external rotator muscles were repaired, two 26-gauge wires were stitched as a marker to the abductor tendons and short external rotator tendons. The distance between the two opposing reference points was less than 1.2 cm. The distance between the markers was determined on radiographs that were obtained 1 day, 2 weeks, and 3 months post-operatively. A distance of more than 2.5 cm, or an invisible one, indicated failure. Results: Of a total of 52 repaired short external rotator muscles, 45 (86.5%) failed. Twenty-five(48.1%) failed within the first day, 15 (28.8%) within 2 weeks, and 5 (9.6%) within 3 months post-operatively. Regardless of the time of failure of the repaired short external rotator muscles, postoperative hip dislocations did not occur. Conclusion: The repair of short external rotator muscles after total hip arthroplasties has a high failure rate and contributes little to the prevention of hip dislocations.

BACKGROUND: We studied the interaction between Succinylcholine (SCh) and mivacurium when mivacurium was administered during early and late recovery from SCh block was investigated. METHODS: Eighty patients undergoing elective surgery under general anesthesia were studied. General anesthesia was induced and maintained with propofol under TCI control. Neuromuscular function was measured in response to TOF stimulation of the ulnar nerve using an electromyographic method. The patients were allocated randomly to the following four groups; group 1 (n = 20): a bolus intravenous injection of 0.08 mg/kg mivacurium; group 2 (n = 20): intravenous injection of 0.08 mg/kg mivacurium after 2 minutes of 1 mg/kg SCh injection; group 3 (n = 20): intravenous injection of 0.08 mg/kg mivacurium after 25% recovery of initial twitch height from twitch height depression induced by 1 mg/kg SCh; group 4 (n = 20): intravenous injection of 0.08 mg/kg mivacurium after 75% recovery of initial twitch height from twitch height depression induced by 1 mg/kg SCh. The onset and duration of neuromuscular blockade, recovery rate and TOF ratio at T75% were measured. RESULTS: The onset of block in groups 3 and 4 were slower than in group 1 (5.2 +/- 0.7 and 2.3 +/- 0.6 vs 2.5 +/- 0.4 min P < 0.05). The clinical duration in groups 2 and 3 were longer than in groups 1 and 4 (12.5 +/- 2.1 min and 11.3 +/- 1.7 min vs 17.0 +/- 3.0 min and 18.5 +/- 2.6 min, p < 0.05). There was no difference in recovery index all groups. The TOF ratio of groups 2, 3 and 4 were smaller than for group 1 (38.2 +/- 5.3, 32.3 +/- 5.6 and 31.5 +/- 4.2 vs 56.0 +/- 7.3, P < 0.05). CONCLUSIONS: The Previous 1 mg/kg SCh injection was affected the time course of action of mivacurium 0.08 mg/kg-induced neuromuscular block.

Generalized plane xanthoma is a group of plane xanthomas that appear as yellow to yellowish-brown flat patches or slightly-elevated plaques with a wide-spread distribution. This disease is not common and may occur in hyperlipidemic or nomolipidemic states. Generalized plane xanthoma with normolipidemia is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown siginificance (MGUS). We report a case of generalized plane xanthoma associated with monoclonal gammopathy of unknown siginificance in a 40 year-old man.
