Due to the anesthesia process is inappropriate on the operation, awakening state was appeared. Because of that patients suffered from severe mental and physical pain. To prevent the state, it is necessary to monitor the patients by measuring the depth of anesthesia. In this study, we investigate the possibility of the development of actual surgery available quantitative indicators. The DFA(detrended fluctuation analysis) which is included the correlation property of the EEG is used to analysis the depth of anesthesia and bispctrum index. In the results, at the pre-operation, the peak of bispectrum was widely distributed, DFA value was decreased. At the during operation, bispectrum was concentrically appeared in the low frequency area. At the post operation, bispectrum and DFA was both returned to the pre-operation state. As a result, we confirmed to be close correlation between the peaks of the bispectrum and DFA value.

This study examined the effects of favorite music therapy on the anxiety and vital signs at each point in gynecologic surgery using the general anesthesia. The research design was a non-equivalent control group non-synchronized design. The data were collected from May 1 to July 30, 2013 and the participants were 44 patients (experimental group, 21, control group, 23) received music therapy while waiting for anesthetic induction and PACU (Post Anesthesia Care Unit). Repeated measures ANOVA was performed to analyze the data by SPSS 18.0. Music therapy reduced the anxiety level at inducing the anesthetic time, and awakening time (p=.003; p=.011). The systolic blood pressure maintained stability at discharge from the PACU (p=.023), and pulse rate was stable at the awakening time (p=.016). This findings support the use of music as a nursing intervention to reduce anxiety and maintain the vital signs for gynecologic surgery patients under general anesthesia.

Multiple caries in a pediatric patient often requires dental treatment under general anesthesia, especially when the patient is suffering from a systemic disease. The patient was a 6-year-old boy with Marfan syndrome and needed extensive dental treatment. Marfan syndrome is an inherited disorder resulting from mutations in Fibrillin-1 gene. Patients are known to have mainly cardiovascular, ocular, and musculoskeletal problems. Although clinical symptoms of the syndrome are age-realted, thus hindering early diagnosis of the disease in young children, our patient had been confirmed by a gene study at a younger age. Medical history of the patient revealed moderate to severe mitral regurgitation and aortic root dilatation, which required mitral valve replacement surgery with a mechanical valve. As a result, the patient was taking warfarin post-operatively and changes in medication had to be made before the dental treatment. Also, prophyalctic antibiotics had to be given before the treatment for prevention of (to prevent the) infective endocarditis. With careful control of the medications and bleeding tendency, general anesthesia and the treatment were done successfully without any complications.

Background: Inguinal hernia repair is one of the most commonly performed surgical procedures. Regional blocks might provide excellent analgesia and reduce complications in the postoperative period. We aimed to compare the postoperative analgesic effect of the ultrasound-guided transversalis fascia (TF) plane block versus the transmuscular quadratus lumborum (QL) block in patients undergoing unilateral inguinal hernia repair. Methods: Fifty patients enrolled in this comparative study and were randomly assigned into two equal groups. One group received an ultrasound-guided QL block. In comparison, the other group received an ultrasound-guided TF plane block. The primary outcome was the patient-assessed resting, and movement-induced pain on the numeric pain rating scale (NRS) measured at 30 minutes postoperatively. Secondary outcomes included the percentage of patients receiving rescue analgesia in the first postoperative day, ease of performance of the technique, and incidence of adverse effects. Results: There were no statistically significant differences in NRS at rest and with movement between the groups over the first 24 hours postoperatively. The proportion of patients that received postoperative rescue analgesics during the first 30 minutes postoperatively was 4% (n = 1) in the QL group compared to 12% (n = 3) in the TF group. However, the mean performance time of the TF block was shorter than that of the QL block, and the performance of the TF block appeared easier technically. Conclusions: The ultrasound-guided TF plane block could be as effective as the QL block in lowering pain scores and decreasing opioid consumption following non-recurrent inguinal herniorrhaphy.

Plastic surgery around the eyes is usually performed under local anesthesia, using a mixture of lidocaine and epinephrine. Blindness is a rare but devastating complication after the injection of local anesthesia in this region. Most cases reported to date have been caused by occlusion of the ophthalmic artery or central retinal artery. In this case report, however, we present a highly unusual case of blindness caused by corneal edema after a local anesthetic injection. A patient visited the emergency room with a laceration on the eyebrow, and local anesthesia was injected before suturing. Immediately after the injection, severe corneal edema developed, making it impossible to observe the structures in the anterior chamber in detail or check the light reflex and visual acuity of the naked eye. An antibiotic (moxifloxacin hydrochloride) and high-concentration steroid eyedrops were promptly applied. High-concentration steroids were also administered orally. On day 13 post-injury, the visual acuity of the naked eye improved to 1.0, and no recurrence of corneal lesions was observed. Although the cause of corneal edema after the local injection could not be conclusively identified, we hope that this report will help raise clinicians' awareness of this complication and appropriate treatment methods.

Post-traumatic anterior open bite can occur as a result of broken balance among the masticatory muscles. The superior hyoid muscle group retracts the mandible downward and contributes to the anterior open bite. Denervation of the digastric muscle by injection of botulinum toxin type A (BTX-A) can reduce the power of the digastric muscle and help to resolve the post-traumatic anterior open bite. A patient with a bilateral angle fracture had an anterior open bite even after undergoing three operations under general anesthesia and rubber traction. Although the open bite showed some improvement by the repeated operation, the occlusion was still unstable six weeks after the initial treatment. To eliminate the residual anterior open bite, BTX-A was injected into the anterior belly of the digastric muscle. Following injection of BTX-A, the anterior open bite showed immediate improvement. Complication and relapse were not observed during follow-up. Long-standing post-traumatic open bite could be successfully corrected by injection of BTX-A into the anterior belly of the digastric muscle without complication.

For a minimally invasive approach to access the facial nerve, we designed an extended epitympanotomy via a transmastoid approach that has proven useful in cases of traumatic facial nerve palsy and pre-cholesteatoma. To evaluate the surgical exposure through an extended epitympanotomy, six patients with traumatic facial nerve palsy were enrolled in this study. The same surgical technique was used in all patients. Patients were assessed and the degree of facial nerve paralysis was determined prior to surgery, 1-week post-operatively, and 6-months post-operatively using the House-Brackmann grading system. In all cases, surgical exposure was adequate. All patients with traumatic facial nerve palsy were male and the age range was 13 to 83 years. In all cases, the location of the facial nerve damage was limited to the area between the first and second genu. Symptoms of all the patients improved by 6 months post-operation (p=0.024). There were no complications in any of the patients. Extended epitympanotomy is useful for safe, rapid surgical exposure of the attic area, sparing the patient post-operative dimpling, skin incision complications, and lengthy exposure to anesthesia. We suggest that surgery for patients with facial nerve palsy secondary to trauma be performed using this described technique.

During the past 3 years, 15 patients who could not be anesthetized generally because of poor general condition or cachecic state, of 111 patients with empyema, have been treated with modified Eloesser`s operation under the local anesthesia with 2% procaine. There were 13 males and 2 females ranging from 21 years to 61 years of age. The etiology was tuberculosis [6 cases], pyogenic pneumonia [5 cases], lung abscess [1 case], post-trauma [2 cases] and malignancy[1 case]. " The over-all mortality rate was 6.7%[1 case] and cause of its death was poor oral feeding because of post-traumatic psychosis. Modified Eloesser`s operation was performed after closed tube thoracostomy and irrigation with 1% zephanon solution for over 2 weeks. And then the other operation was not performed and all patients except 1 case appeared good progression (Complete healing; 4 cases, Progressive healing 10 cases, death: 1 case).
