Epidural block under general anesthesia has been widely used to control postoperative pain. In this anesthetic state many hemodynamic parameters are changed. Moreover pulse transit time is influenced by this memodynamic change. m change in the finger and the toe due to relaxation of arterial wall muscle after general anesthesia and epidural block under general anesthesia. This study, in the both general anesthesia and epidural block under general anesthesia, ${\Delta}PTT$ of the toe and of the finger are measured. In addition, ${\Delta}PTT$(toe-finger) of the epidural block under general anesthesia and of the general anesthesia were compared.

We present our experience with the use of nerve block anesthesia in 212 of 484(43.8% ) surgical procedures of the foot and ankle between 1995 and 1997. Nerve block anesthesia was used for surgical procedures of the forefoot, midfoot, hindfoot, and ankle in the setting of elective surgery and trauma. From the viewpoint of the surgeon, nerve block anesthesia was completely successful in 99.5% of the procedures performed. We confirmed that 80% of patients were satisfied with the use of nerve block anesthesia for their operative procedure. There were only one(0.5%) miner complication being toxic neuritis of posterior tibial nerve. With increasing experience, the expanded indications and uses of nerve block anesthesia for foot and ankle surgery are proving to be simple, safe, reliable, and well tolerated by the patient.

The inferior alveolar nerve (IAN) block is the most frequently used mandibular injection technique for achieving local anesthesia for restorative and surgical procedures. However, The IAN block does not always result in successful anesthesia, especially pulpal anesthesia. Lidocaine is used as a "standard" local anesthetic for the inferior alveolar nerve. Articaine recently joined Korean market as a form of dental cartridge. It has an advantage of superior diffusion through bony tissue. A variety of trial was performed to improve the success rate of inferior alveolar nerve block. In this review, the recent update related with inferior alveolar nerve block anesthesia will be discussed on the anatomical consideration, anesthetic agent, technique, and complications.

Background: Circumcision is a painful intervention frequently performed in pediatric surgery. We aim to compare the efficacy of caudal block versus dorsal penile block (DPNB) under general anesthesia for children undergoing circumcision. Methods: This study was performed between July 1, 2009 and October 16, 2009. Fifty male children American Society of Anesthesiolgists physical status classification I, aged between 3 and 12 were included in this randomized, prospective, comparative study. Anesthetic techniques were standardized for all children. Patients were randomized into 2 groups. Using 0.25% 0.5 ml/kg levobupivacain, we performed DPNB for Group 1 and caudal block for Group 2. Postoperative analgesia was evaluated for six hours with the Flacc Pain Scale for five categories; (F) Face, (L) Legs, (A) Activity, (C) Cry, and (C) Consolability. For every child, supplemental analgesic amounts, times, and probable local or systemic complications were recorded. Results: No significant difference between the groups (P > 0.05) was found in mean age, body weight, anesthesia duration, FLACC pain, and sedation scores (P > 0.05). However, on subsequent measurements, a significant decrease of pain and sedation scores was noted in both the DPNB group and the caudal block group (P < 0.001). No major complication was found when using either technique. Conclusions: DPNB and caudal block provided similar postoperative analgesic effects without major complications for children under general anesthesia.

Subdural block is a rare but well recognized complication of epidural anesthesia. The placement of local anesthetics into the subdural space can lead to potentially life-threatening conditions. A healthy 46-year-old women underwent total abdominal hysterectomy under continuous lumber epidural anesthesia. The technical procedure for continuous epidural catheterization went smoothly without a single problem. However, signs of high epidural block such as apnea, cranial nerve paralysis and pupil dilatation developed gradually, about 20 minutes after the epidural injection of 2% lidocaine 20 ml through the epidural catheter. Such extensive segmental block can only be explained as the result of injection into subdural space even if it was not confirmed radiologically.

The purposes of this study were to evaluate and compare the pulpal anesthesia induced by an inferior alveolar nerve block and that by Gow-Gates technique, and to investigate the relationship between pulpal anesthesia and intraoral soft tissue responses. After one side of mandibule was anesthetized with inferior alveolar nerve block or Gow-Gates technique using 2 % lidocaine with 1 : 100,000 epinephrine in 19 volunteers of ages between 24 and 29 (16 males and 3 females, average age 25.9 yrs.), electric pulp tests were done on the canine teeth of the anesthetized side and contralateral one before, at 1 min, continued at every 5 minutes until 60 min, and every 10 minutes until 100 min after completion of local anesthetic injection. Degree of pulpal anesthesia was classified as anesthetic failure, possible anesthesia and complete anesthesia by the criteria based on the thresholds to electric pulp test of contralateral canine and the currents of the electric pulp tester. Subjective signs on the lower lip and tongue were checked and prick-pin tests were done on the buccal gingiva of the first molar, buccal and lingual gingiva of the canine tooth at 5, 10 and 20 min after the completion of anesthetic injection. Thresholds to electric pulp test, degree of pulpal anesthesia and relationship between the pulpal anesthesia and soft tissue responses were analyzed with SPSS, paired t-test, Wilcoxon matched-pairs signed-ranks test and correlation analysis. The results were as follows : No significant differences were found in the peak thresholds to electric pulp test, in the induction time to it and in the depth of pulpal anesthesia between inferior alveolar nerve block and Gow-Gates technique (p>0.05). There was no significant relationship between pulpal anesthesia and soft tissue responses in both inferior nerve block and Gow-Gates technique.

The most widely used method of pain control in dental practice is to block the pathway of painful impulses by local anesthesia. For a maximum effect of pain control at outpatient minor operation, regional anesthesia including nerve block must be performed. This issue includes various dental local anesthetic techniques on mandible, maxilla and considerations for selection of dental local anesthetics according to patient's age, duration of operation. Additionally, current conscious sedation technique combined with local anesthesia will be introduced for control of patient's anxiousness. Based on patient's general condition, severity of operation, local anesthesia sometimes must be changed into general anesthesia to avoid failure of dental practice. The exact choice of anesthetic techniques for minor operations at dental outpatient clinic must not be underestimated for complete success of pain control.

Inferior alveolar nerve block anesthesia is one of the most common procedures in dental clinic. Although it is well known as safe procedure, complications always can be occurred. Ocular complications such as diplopia, loss of vision, opthalmoplegia are very rare, but once it happens, dentist and patient can be embarrassed and rapport will be decreased between them. We experienced one diplopia case after inferior alveolar nerve block anesthesia and treated without any further complication. We report this case and describe the cause, diagnosis, and treatment objectives of diplopia caused by inferior alveolar nerve block anesthesia.

Total spinal anesthesia is a serious life threatening complication of spinal and epidural anesthesia. We report an accidental total spinal anesthesia developed during a thoracic epidural block in a practitioner's pain clinic. A 69-year-old female with post-herpetic neuralgia was treated by a thoracic epidural block. A thoracic tapping for the epidural block was performed in the right lateral position at a level between $T_{5-6}$, using a 23 gauge Tuohy needle. After the epidural space was identified, a mixed solution of 10 ml of 0.3% lidocaine and 20 mg of triamcinolone was injected into the epidural space. After removal of the syringe, fluid was dripping through the needle. The patient subsequently complained of dyspnea and dizziness, and she became unconscious. She was intubated immediately and cardiopulmonary resuscitation was performed because there was no pulse palpable. The patient recovered an hour after transfer to a general hospital and was discharged without any further complication 19 days later.
