In order to establish optimum anesthesia concentration, we tested the efficacy of clove oil at five different concentrations in large sized (mean SL $17.1{\pm}2.21\;cm$) and small sized (mean SL $0.6{\pm}0.06\;cm$) dark-banded rockfish Sebastes inermis. Optimal anesthesia concentration for dark-banded rockfish was $150\;mgL^{-1}$ in both large and small sized fish. In general, fish exposed to higher anesthetic doses were rapidly induced but took longer to recover (P<0.05). Recovery time of small sized fish was longer than large sized fish in lower concentrations, while recovery time of large sized fish was longer than small sized fish in higher concentration (P<0.05). Using the established optimum aesthetic concentration, we evaluated the physiological response of dark-banded rockfish to clove oil by measuring plasma cortisol and glucose levels. Following administration of $150\;mgL^{-1}$ clove oil at $20^{\circ}C$ (optimum breeding temperature), plasma cortisol level was highest ($42.2{\pm}11.318{\mu}g/dL$) after 0 hour, while plasma glucose level was highest ($52.5{\pm}10.61\;mg/dL$) after 1 hour. Plasma cortisol and glucose concentrations required 6 and 2 hours, respectively, to return to pre-exposure levels.

To evaluate butorphanol and tramadol as adjuvants to lidocaine in dogs undergoing mandibular nerve block. Fifteen beagles were allocated to groups based on the following treatments: lidocaine alone (L group), lidocaine + butorphanol (LB group), or lidocaine + tramadol (LT group). After mandibular nerve block with opioids as an adjunct to local anesthetics, the onset time, duration of action, and depth of anesthesia were evaluated using a quantitative method through neuromuscular blockades (NMBs) monitoring. The onset time of nerve block was 4.60 ± 2.06 min, 2.00 ± 0.00 min, and 2.60 ± 1.62 min in the L, LB, and LT groups, respectively; however, there was no statistically significant difference. The duration of nerve block was 111.88 ± 34.78 min, 302.00 ± 76.72 min, and 260.40 ± 49.88 min in the L, LB, and LT groups, respectively, with a significant difference between L and LB groups. The LB group demonstrated a more profound depth of anesthesia compared to the L and LT groups. In this study, using a quantitative method through NMBs monitoring, it was demonstrated that lidocaine and butorphanol in combination can increase the duration of nerve block and more profound the depth of anesthesia rather than lidocaine alone. Additionally, the combined use of lidocaine and opioids presented an objective indicator that could provide a more clinically stable nerve block.

Background: In human dentition, the most commonly impacted teeth are the mandibular third molars (M3M). The removal or extraction of these teeth often causes anxiety in patients due to the perceived pain involved in the process. Therefore, pain must be effectively managed using anesthesia. The use of newer local anesthetic drugs can help minimize side effects and drug interactions. Traditionally, adrenaline is used as a vasoconstrictor along with lignocaine. When combined with lignocaine, the alpha agonists dexmedetomidine and clonidine can extend the duration of anesthesia, thereby reducing the need for additional pain-relieving medications. Methods: This study used a randomized, triple-blind, parallel-arm design. Sixty patients were screened, and 45 systemically healthy patients requiring unilateral surgical removal of impacted mandibular third molars with similar difficulty (moderate-to-difficult according to the Modified Pederson's Index) were included in the study. Patients were allocated into three groups as follows: Group A: 2% Lignocaine Hydrochloride with 1:100,000 Adrenaline, Group C: 2% Lignocaine Hydrochloride with 15 ㎍/mL Clonidine, and Group D: 2% Lignocaine Hydrochloride with 1 ㎍/mL Dexmedetomidine. The evaluated parameters were the time of onset of anesthesia, depth of anesthesia, hemodynamic parameters, and duration of postoperative analgesia. Results: Group D had a faster onset of action and prolonged duration of postoperative analgesia compared with Groups A and C. No statistically significant differences were observed between the three groups in terms of the depth of anesthesia and hemodynamic parameters. Conclusion: Group D exhibited a significantly more rapid onset of anesthesia than Groups A and C, and the postoperative analgesic effect in Group D was significantly prolonged (7.22 hours) compared with that in Groups A (4.54 hours) and C (2.1 hours). Patients receiving the Group D solution experienced an extended period of comfort without the need for analgesics for up to 7.22 hours post-procedure.

To study effective dossage and administration route for scaling, ketamine HCl/propionyl promazine HCl(ketamine) combination and tiletamine HCl/zolazepam HCl(zoletil) were administered in one hundred six dogs. The dogs were toy poodle, Yorkshire Terrier, Pekingese and Chihuahua. Scaling and polishing time, possible treatment time after the first injection of anesthetics, the number of anethesia added, presence of tongue movement during anesthesia, the presence of swaying sign during recovery and respiration were evaluated. The possible treatment time after the first Injection of anesthetic in toy poodle were 26.3${\pm}$3.0 minutes with intravenous(IM) treatment of ketamine 10mg/kg, and 21.4${\pm}$6.6 minutes with intramuscula(IM) treatment of zoletil 8mg/kg, In Yorkshire Terrier were 19.51: 1.7 minutes with IV treatment of ketamine 10mg/kg. 19.0${\pm}$5.2 minutes IM and 20.8${\pm}$6.1 minutes with IM treatment of zoletil 5mg/kg,24.8${\pm}$3,5 minutes with IM treatment of zoletil 8mg/kg. In pekingese were 27.5${\pm}$2.1 minutes with IM treatment of ketamine 10mg/kg,28.0${\pm}$4.2 minutes with IM treatment of zoletil 8mg/kg. In Chihuahua were 19.5${\pm}$1.9 minutes with IV treatment of ketamine 7mg/kg, 17.5${\pm}$1.7 minutes with IM treatment of ketamine 10mg/kg and 20.3${\pm}$3.8 minutes with IM treatment of zoletil 5mg/kg, 21.2${\pm}$5.5 minutes with IM treatment of zoletil 8mg/kg. Swaying sign was observed in all group during recovery time, espically, in toy poodle and Yorkshire Terrier which administered zoletil 8mg/kg IM showed more severe swaying sign. The present results suggested that injection of zoletil 8mg/kg IM might be relatively effective for scaling in Chihuahua Within 20 minutes treatment for scaling in Yorkshire Terrier and Chihuahua, IM treatment of ketamine 7 to 10mg/kg is recommended.

There is a system in Korea named "Advanced Practice Nurse System" qualified by the Minister of Health, Welfare and Family Affairs for Advanced Practice Nurse besides nurse licence. Medical practice is, in today's medical law, understood as a general concept colligating medical practice, nursing practice and midwife practice and so on, for it is defined as a deed of medical technique practiced by medical personnel. Referring to the fact that the Supreme Court recognizes medical personnel as people who have medical expert knowledge, nursing practice can be recognized as a region of medical business and therefore it is not necessary to prescribe nursing practice separately from the definition of medical practice on a precedent, because nurse belongs to medical personnel. According to the precedent regarding 'Unlicensed Medical Practice of Advanced Practice Nurse for Anesthesia' recently sentenced by the Supreme Court, the medical practice is only allowed a doctor because it is 'in need of special knowledge and experience because of high danger on human body' and it is judged to be an unlicensed medical practice prohibited in medical law if it is to be done by a nurse. When considering the actual situation that System for Advanced Practice Nurse for Anesthesia is established under the circumstance that an anesthetist is in want and therefore the operation has not been performed on time, and that it is being expected an anesthetist to be in need, it is necessary to legislate for the range of medical practice of Advanced Practice Nurse so that Advanced Practice Nurse System can be practically legalized, for the role of Advanced Practice Nurse has the great possibility of shrinking because the precedent has considered Advanced Practice Nurse for Anesthesia doing anesthetic operation in clinic today as a potential wrongdoer.

Purpose: This study was conducted to compare three discharge criteria; 1) discharge criteria of S Hospital determined by nurses, 2) discharge readiness determined by patients, and 3) the Modified Post-Anesthetic Discharge Scoring System (MPADSS). The usefulness of MPADSS as a discharge criteria for the patients'safe return to home after ambulatory surgery was also evaluated. Methods: A total of 370 day surgery cases were investigated. The MPADSS was employed in every 30 min. in parallel with discharge readiness assessment by nurses and patients. The percentage of the patients who were categorized as being ready to discharge were compared according to three discharge criteria. Results: The percentage of patients scored to be as MPADSS > 9 in 30 min, 60 min, 90 min were 96.5%, 99.5%, 100%respectively. Whereas 11.1%, 44.3%, 71.1%of patients rated themselves as being ready to discharge and 2.7%, 23.5%, 54.3% of patients actually discharged by nurses according to discharge criteria of S Hospital. Conclusion: Nurses tend to keep patients longer in the hospital when compared to the patient's own assessment about their readiness to home and to that of MPADSS. Faster discharge in the evening than day time suggests patient discharge can be influenced by nursing factors. This brings out the importance of scoring system to determine the safe discharge. The MPADSS could be a useful tool in evaluating patients for safe discharge.

연구배경 : 식도암은 근치율이 낮고, 광범위 림프절 절제후에도 그 성적이 나쁜 편이다. 따라서 경부 림프절 절제가 식도수술결과에 미치는 효과를 알아보고자 식도수술 환자에서 경부림프절 전이가 된 환자를 조사하였다 대상 및 방법 : 1994년부터 1996년 6월까지 본원에서 흉부식도암 수술을 받은 32명의 환자 중 고식적 수술을 시행받은 25명의 환자를 대상으로 하여 경부림프절 절제의 유무를 기준으로 두 그룹으로 나뉘어 연구하였다. 두 그룹 모두 흉부식도 전절제술과 동반하여 종격림프절과 복부림프절 절제를 시행하였으나 B그룹은 양측 경부림프절 절제를 추가하여 시행하였다. 결과 : 수술합병증은 두 그룹 사이에서 의미있게 차이가 나지않았다. t수술사망과 병원사망은 두 그룹 모두에서 보이지 않았다. 그러나 평균 마취시간은 B그룹에서 의밌게 더 길었다.(평균 마취시간 90분). B그룹에서 27%가 경부림프절 전이를 보였다 결론 : 그러므로 경부림프절 절제는 흉부식도암 수술에서 의미있는 수술방법이라고 할 수 있다. 장기생존율의 비교가 더 필요하리라고 생각한다.

Background: Vascular occlusive event is one of the etiologies of sudden sensorineural hearing loss (SNHL). Stellate ganglion block (SGB) induces dramatic and intense vasodilatation in head and neck. Based on this principle, SGB has used as one of the treatment modalities in SNHL. This study was performed to evaluate immediate response of SGB on pure tone audiogram (PTA) in SNHL. Methods: Forty patients were studied. Each patient received daily ipsilateral SGB in paratracheal approach using 0.2% bupivacaine for 2 weeks. On first, third, and fifth day of treatment, we checked their PTA twice 1 hour before (Pre-PTA) and after (Post-PTA) SGB. Pre- and Post-PTA were compared. Several factors were analyzed as a prognostic factor of therapeutic results. Results: Eleven of 40 patients revealed decreased PTA after SGB. Degree of decreased PTA were insignificant ($2.5{\pm}1.6$ dB). Initial and final PTA results was $76.2{\pm}22.5$ and $49.8{\pm}28.3$ dB, respectively. Thirty-one of 40 patients were improved their PTA over 10 dB. The recovery was mainly influenced by the severity of initial hearing loss (P<0.001) and slightly by age (P<0.05). However, the change of PTA after SGB, time interval to receive SGB, sex, site, and number of SGB were not correlated to therapeutic outcome. Conclusions: These results suggest that vasodilatation by SGB has no immediate improvement in SNHL. Therefore, we question whether SGB is beneficial to all patients with SNHL as a therapeutic modality.

Purpose: This prospective study was designed to investigate the incidence of acute postoperative pain (APP) ${\geq}4$ and the risk factors of APP${\geq}$ for the first 48 hours after surgery. Methods: Data from 531 surgical patients were collected from November, 2009 to May, 2010. APP was assessed from the time of arrival at the Post Anesthetic Care Unit (PACU) to the end of the post-operative 48 hours. Risk factors of APP${\geq}$ were analyzed by logistic regression analysis. Results: The incidence of APP ${\geq}4$ was 58.8% for the first postoperative 4 hours; 33.5%, 24 hours; 11.1%, 48 hours. The score of pain was 5.55, the highest on arriving at PACU; 5.03 at postoperative 30 minutes; 4.03 at 1 hour; 3.96 at 4 hours; 2.76 at 24 hours; 1.44 at 48 hours Risk factors for APP ${\geq}4$ were females (Odds ratio [OR], 1.94; p=.013), general anesthesia (OR, 4.29; p<.001) and patient controlled analgesia (PCA) (OR, 2.83; p<.001) at 4 hours after operation; body mass index (BMI) ${\geq}25$ (OR, 1.80; p=.009), duration of surgery ${\geq}1$ hour (OR, 2.87; p=.037), general anesthesia (OR, 3.99; p<.001) and PCA (OR, 6.23; p<.001) at 24 hours; general anesthesia (OR, 3.53; p=.003) and PCA (OR, 3.01; p=.013) at 48 hours. Conclusion: Surgical patients with BMI ${\geq}25$, PCA and general anesthesia seem to have a higher incidence of pain ${\geq}4$ through the first postoperative 48 hours.
