Background: In addition to causing the loss of voluntary sensory and motor function, spinal cord injury (SCI) often creates a state of central neuropathic pain. Rats given SCI display increases in the activated form of transcription factors ERK 1/2, p38 MAPK, and CREB in the spinal cord, which correspond to allodynia in a model of neuropathic pain. The current study was designed to determine if lidocaine had an effect on the development of neuropathic pain in response to SCI. Methods: Male Sprague Dawley rats were anesthetized and then received a L5-L6 spinal nerve ligation (neuropathic rats). The levels of intracellular cell-signaling protein, ERK 1/2 and CREB were then assessed by western blot analysis of samples collected from a sham operated (control) group, a neuropathic pain and normal saline (NP+NS) group, and a neuropathic pain and 5% lidocaine (NP+Lido) group. Results: The increased levels of ERK 1/2 and CREB protein that were observed in the neuropathic pain model were reduced by continuous infusion of 5% lidocaine. Conclusions: The current results suggest that lidocaine therapy may be an effective method of preventing and treating central neuropathic pain following SCI, and that these effects may occur via the reduced expression of ERK 1/2 and CREB in the intracellular cell-signaling pathway.

Background: Acute renal failure (ARF) results from renal ischemic reperfusion (IR) injury and is a major contributor to the morbidity and mortality encountered during the perioperative period. It was previously demonstrated that ischemic preconditioning (IPC) of the heart, brain, and kidney offered protection against IR injury. Therefore, this study examined whether or not distant IPC can also be effective against IR injury in other organs. Methods: C57BL6 mice were classified into three groups, Sham group (n = 7), IR group (n = 7) and Cross IPC IR group (n = 7). The sham group was subjected only to a right renal nephrectomy (ligation of renal pedicle with silk). The IR group was subjected to 30 min of left renal ischemia after a right nephrectomy. The cross IPC IR group was subjected to right renal IPC (two cycles of 5 min of ischemia and reperfusion) followed 15 min later by a right nephrectomy and 30 min left renal ischemia. The left kidney was harvested 24 h after surgery and the histology and blood creatinine level was analyzed. The left kidneys were isolated 15 min after right nephrectomy (sham, n = 7) and right renal IPC (cross IPC, n = 7), respectively, and analyzed by western blotting. Results: The level of the intra-cellular signaling proteins, iNOS, Akt and ERK increased significantly as a result of the right renal IPC, and the renal functions were well preserved in the cross IPC IR group compared with the IR group. Conclusions: Cross renal IPC offers protection by elevating the iNOS, Akt and ERK levels due to the distant oxygen free radicals stream against the opposite renal IR injury in mice.

Objective : We searched the incidence of postoperative nausea and vomiting(PONV) after microvascular decompression(MVD), which might potentially results in an increased risk of postoperative intracranial hemorrhage and neurologic dysfunction. METHODS : Between 2004 and 2010, a total of 109 patients were diagnosed as having a neurovascular cross compression, and were treated with lateral suboccipital craniotomy with MVD. The incidence of PONV and the use of rescue antiemetics were identified at 1, 24 and 48 hours after surgery. RESULTS : Seventy-one(65.1%) patients were female, and the mean age of the patients was 49±10 years(range, 20~69). The overall incidence of development of PONV within postoperative 48 hours was 69.7%. The incidences of PONV at 1, 24, and 48 hours after surgery were 31.1%, 56.8%, 44.0%, respectively. PONV was most prevalent at 24 hours after surgery, and then the incidence decreased over time. In the early postoperative period, female was significantly more susceptible to PONV than male, especially at 1 hour after surgery(p=0.035). CONCLUSION : The incidence of PONV was high enough to be actively managed, especially within 24 hours after MVD. PONV was more prevalent in female in the early postoperative period.
마취통증의학과 영역에서 Intra-cellular Signaling Pathway의 이용
주진덕 ( Jin Deok Joo ) 대한마취과학회 2009 Korean Journal of Anesthesiology Vol.57 No.3
At the level of individual cells, signaling is crucial in cell division, differentiation, metabolic control and death. Reception of the signals depends on receptor proteins that are usually at the cell surface, and these receptor proteins bind the signal molecule. The binding activates the receptor, which in turn activates one or more of the intra-cellular signaling pathways. These relay chains of molecules, mainly intra-cellular signaling proteins, process the signal inside the receiving cell and distribute it to the appropriate intra-cellular targets. Cell signaling pathways are involved in the pathophysiology of many diseases and also in the mechanisms of action of many drugs, including local and general anesthetics. Knowledge of the basic cell signaling mechanisms is essential for understanding many of the pathophysiologic and pharmacologic mechanisms. Therefore, if we focus on applying the new cellular and molecular biologic research, these efforts could identify the mechanism of diseases and help develop new drugs in the field of anesthesiology and pain medicine.

Background: Propofol has been the most widely used IV adjuvant during Monitored anesthesia care (MAC), even though it lacksanalgesic properties. This study was designed to compare sedation quality, side effects, and recovery profiles of propofol alone (group P), propofol-fentanyl (group PF) and propofol-ketamine (group PK) using PCS for breast biopsy procedures using local anesthesia. Methods: Anxiety VAS, pain VAS and digit symbol substitution test (DSST) were measured in 60 excision breast biopsy patients with local anesthesia. Vital signs, respiratory (SpO2, RR, and ETCO2) variables, BIS, and OAA/S scores were recorded. Perioperative side effects (e. g., pain on injection, excessive sedation [OAA/S < 4], hypoventilation [ventilatory frequency 8 bpm], hypotension, dizziness, unpleasant feeling, Nausea) were also noted. Results: There were no differences among the three PCS groups with respect to demographic data (Table 1). A/D ratio in PK group had a significant increase over P group. The incidence of excessive sedation and dizziness were significantly more frequent in the PK group patients (P < 0.05)(Table 1, 2). OAA/S scores were significantly decreased in the PK group during near the end of surgery, whereas BIS scores were only at the end of surgery (P < 0.05)(Fig. 1, 2). During 15 min after arrival at recovery room, significantly less patients in the PK group gave correct responses on the DSST than other groups (P < 0.05)(Fig. 2, 3). Conclusions: In contrast to past studies of ketamine as an alternative to opioid adjuncts during propofol PCS, it has no more advantage than supplemental fentanyl in terms of sedation level and side effects.

Background: In addition to causing the loss of voluntary sensory and motor function, spinal cord injury (SCI) often creates a state of central neuropathic pain. Rats given SCI display increases in the activated form of transcription factors ERK 1/2 MAPK and CREB in the spinal cord, which correspond to allodynia in a model of neuropathic pain. This study was conducted to determine if low dose ketamine had an effect on the activation of ERK 1/2 and CREB in the development of neuropathic pain. Methods: This study was conducted to evaluate ERK 1/2 and CREB protein in a sham operated (control) group, neuropathic pain and normal saline (NP+NS) group and neuropathic pain and ketamine (NP+Keta) group. To accomplish this, male Sprague-Dawley rats were anesthetized and then subjected to L5-L6 spinal nerve ligation (SNL, neuropathic rats). The total amounts of ERK 1/2 and CREB protein were then assessed by western blot analysis. In addition, changes in the amounts of ERK 1/2 and CREB mRNA were evaluated by RT-PCR. Results: There was a significant increase in the amount of ERK 1/2 and CREB in the NP+NS group when compared with the sham group. However, the amount of ERK 1/2 and CREB protein induced due to SNL were significantly reduced by continuous infusion with ketamine in the NP+Keta group. Conclusions: The results of this study revealed a positive linkage between NMDA receptors and the ERK-CREB signaling pathway. Therefore, NMDA receptors could be the target of future therapeutic approaches. Additionally, the results of the present study provide additional evidence that low dose ketamine effectively prevents and treats central neuropathic pain following SNL.

Background: Postoperative pain degree is variable according to the site, type, and method of operation. This study compared the pain degree and amount of analgesics required among 3 types of operation. Methods: Ninety patients were selected that cesarean section (Group I, n = 30), open total hysterectomy (Group II, n = 30), laparoscopic total hysterectomy (Group III, n = 30) were scheduled. Patients received PCA with basal rate 2 ml/h, bolus 1 ml, lockout interval 5 min using fentanyl and ketorolac. We evaluated VAS at 30 min, 2, 6, 12, 18, 24, 36, 48 h postoperatively, demand of button and attempt of button, 6 hourly used amount of analgesics; side effects and degree of satisfaction after 24, 48 h postoperatively. Results: The rest VAS decreased below 30 at 6 hr in group I & II and at 2 hr in group III. More analgesics were needed for the first 6 hr compared with remained time in 3 groups (group I vs. group II vs. group III, P < 0.05). Total amount of analgesics including loading dose were fentanyl 1,536 ± 342μg, ketorolac 167 ± 34 mg for group I; 1,212 ± 215μg, 132 ± 30 mg for group II; 866 ± 125μg, 97 ± 27 mg for group III (group I vs. group II vs. group III, P < 0.05). Conclusions: The postoperative pain was painful as order of cesarean section, open total hysterectomy, and laparoscopic total hysterectomy. The pain was reduced 6 hr in laparotomy and 2 h in laparoscopy. (Korean J Anesthesiol 2007; 52: 166~71)
