  • Background: Nonobstetric surgery is sometimes required during pregnancy, and neck abscess or facial bone fracture surgery cannot be postponed in pregnant women. However, dental surgery can be stressful and can cause inflammation, and the inflammatory response is a well-known major cause of preterm labor. Propofol is an intravenous anesthetic commonly used for general anesthesia and sedation. Studies investigating the effect of propofol on human amnion are rare. The current study investigated the effects of propofol on lipopolysaccharide (LPS)-induced inflammatory responses in human amnion-derived WISH cells. Methods: WISH cells were exposed to LPS for 24 h and co-treated with various concentrations of propofol (0.01-1 ㎍/ml). Cell viability was measured using the MTT assay. Nitric oxide (NO) production was analyzed using a microassay based on the Griess reaction. The protein expression of cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE 2), p38, and phospho-p38 was analyzed using western blotting. Results: Propofol did not affect the viability and NO production of WISH cells. Co-treatment with LPS and propofol reduced COX-2 and PGE2 protein expression and inhibited p38 phosphorylation in WISH cells. Conclusion: Propofol does not affect the viability of WISH cells and inhibits LPS-induced expression of inflammatory factors. The inhibitory effect of propofol on inflammatory factor expression is likely mediated by the inhibition of p38 activation.

  • An 87-year-old woman was referred for the extraction of residual teeth and removal of tori prior to prosthetic treatment. After surgery under general anesthesia, the surgical tape was removed to detach the bispectral index sensor and the hair cover. After the surgical tape was removed, skin injury occurred on the left side of her face. After epidermis repositioning and ointment application, a dressing was placed over the injury. Her wound was found to have healed completely on follow-up examination. Medical adhesive related skin injury (MARSI) is a complication that can occur after surgery and subjects at the extremes of age with fragile skin are at a higher risk for such injuries. Careful assessment of the risk factors associated with MARSI is an absolute necessity.

  • Local anesthesia known as the safe and essential procedure to control pain in dentistry may cause sensory changes such as paresthesia or altered taste at the affected sites after even successful local anesthesia. Although the prognosis of the nerve injuries after local anesthesia is favorable, it might cause prolonged problems such as dysesthesia. The lingual nerve is a single fascicle at the level of the lingual among 1/3 of patients and more movable during regeneration compared to the inferior alveolar nerve after the injury. As a result, the lingual nerve is more vulnerable and has poorer outcomes. More vigilant clinical considerations are required to the lingual nerve injury after local anesthesia. Generally, more than 80% of cases are spontaneously resolved within 2 weeks after the local anesthesia even without any specific treatment. However, the patient having long lasting abnormal sensations more than 2 weeks needs specialists' care for further assessment. In case of dysesthesia which is a symptom of neuropathic pain, immediate referral to specialists is mandatory. The exact mechanism, how to prevent its occurrence, or specific treatments of the nerve injury related to the local anesthesia have not been elucidated. To prepare clinical or medicolegal problems, many cautious considerations are given to the patients who complain sensory changes after local anesthesia.

  • Managing pain and anxiety in patients has always been an essential part of dentistry. To prevent pain, dentists administer local anaesthesia (LA) via a needle injection. Unfortunately, anxiety and fear that arise prior to and/or during injection remains a barrier for many children and adults from receiving dental treatment. There is a constant search for techniques to alleviate the invasive and painful nature of the needle injection. In recent years, researchers have developed alternative methods which enable dental anaesthesia to be less invasive and more patient-friendly. The aim of this review is to highlight the procedures and devices available which may replace the conventional needle-administered local anaesthesia. The most known alternative methods in providing anaesthesia in dentistry are: topical anaesthesia, electronic dental anaesthesia, jet-injectors, iontophoresis, and computerized control local anaesthesia delivery systems. Even though these procedures are well accepted by patients to date, it is the authors' opinion that the effectiveness practicality of such techniques in general dentistry is not without limitations.

  • We provided general anesthesia management to a patient with advanced atrioventricular block, which was discovered in the remote period after open-heart surgery. A 21-year-old man with Noonan syndrome was scheduled to undergo excision of a median intramandibular tumor. At 2 months of age, the patient underwent endocardial repair for congenital heart disease. During our preoperative examination, an atrioventricular block was detected, which had not been previously noted. Emergency drugs were administered, and a transcutaneous pacemaker was placed. During anesthesia induction, mask ventilation was easy, and intubation was performed smoothly using a video laryngoscope. The transcutaneous pacemaker was activated in demand mode at a pacing rate of 50 cycles/min approximately throughout the anesthesia time, and the hemodynamic status remained stable. The effect of intraoperatively administered atropine was brief, lasting only a few seconds. Although body movements due to thoracoabdominal muscle spasm were observed during pacemaker activation, they did not interfere with surgery. In postoperative patients with congenital heart disease, an atrioventricular block may be identified in the remote period, and preoperative evaluation should be based on this possibility. In addition, during anesthesia management, it is important to prepare multiple measures to maintain hemodynamic status.

  • A 15-years-old female patient with seizure disorder and pervasive developmental disorder was scheduled for dental treatment under ambulatory general anesthesia. She had past history of pneumonia and herpes encephalitis when she was 3 year old. Because of sever mental retardation and behavior disorder, routine laboratory test was substituted with physical exam and medical records of department of pediatrics. A few days before general anesthesia, she showed slight common cold, but pediatric consult had reported that there was minimal risk in general anesthesia. After 4-hour general anesthesia, she became critically sick with high fever, cough and malaise. After 10-day hospitalization with pneumonia and sepsis, she could go home.

  • In oral and maxillofacial surgery, many complications associated with nasotracheal tube can be caused. In this case, we reported ballooning tube damage of nasotracheal tube during orthognathic double-jaw surgery and replacement of tube through cut down of tube and tube exchange using airway exchange catheter. The patient scheduled for high Le Fort I osteotomy and bilateral sagittal split osteotomy was intubated nasotracheally with nasal endotracheal tube. During maxilla osteotomy, air bubble was detected in the oral blood. In spite of our repeated ballooning, the results were the same so we changed damaged tube using airway exchange catheter aseptically. Tiny and superficial cutting site was detected in the middle of pilot tube. As we know in our case, tiny injury impeded a normal airway management and prevention is important.

  • Regional anesthesia in the maxillofacial region is safer and more efficient than general anesthesia when its indications are carefully considered. In addition, the majority of medical institutions in developing countries are not well equipped for proper anesthesia and elective surgery. In this review, we describe regional anesthesia and cutaneous nerve divisions in the maxillofacial region. In addition, we summarize detailed regional anesthetic techniques adapted for representative cleft lip cases in developing countries.

  • The purpose of this study was to analyze the dental treatment of patients with disabilities, especially according to the frequency of general anesthesia, and to propose the improvements in oral care. The subjects of the present study were 85 patients including age, sex, medical condition, dental treatment and the number of general anesthesia. The patients were divided into regular and irregular check groups according to their follow-up patterns. These two groups were compared for the frequency of general anesthesia and the type of repeated treatment. The results showed that restorative treatment was superior in numbers under first visit of general anesthesia. And more general anesthesia was performed in the irregular recall check group compared with the regular recall check group. This survey suggest that easy access to a dental clinic and the convenience of treatment is needed. On the other hand, there is a time limit on the dental care for disabilities by the dentist. Therefore oral care training program should be simultaneously provided for parents to improve the efficiency of dental care at home. In conclusion, efforts should be made for more comprehensive and effective dental care including regular recall check and preventive home care for disabilities.
