Background: Thoracotomy is the operation that produces the most postoperative pain, necessitating the highest requirements for postoperative analgesics. The common methods of treating postthoracotomy pain are the use of thoracic epidural analgesia, intemittent or continuous intercostal nerve blocks, intravenous narcotics and cryoanalgesia. We designed to assess the analgesic effect of epidural analgesia, cryoanalgesia and the combined analgesia in thoracic surgery. Methods: A prospective study was carried out in 59 patients undergoing elective thoracotomy for parenchymal disease. Patients were randomized into three groups: C (cryoanalgesia), CE (cryoanalgesia and thoracic epidural analgesia), E (epidural analgesia). All patients had standard anesthesia with endotracheal intubation using a double lumen endotracheal tube, and one-lung ventilation. Subjective pain relief was assessed on a visual analog scale. Analgesic requirements, complications and the degree of satisfaction were evaluated during the 7 days following surgery. Results: Subjective pain relief was significantly better in Group CE and Group E in comparison with Group C (P < 0.05). Cryoanalgesia provided a better pain score on the 6th and 7th POD than the early postoperative periods. Analgesic requirements were higher in Group C than in the Group CE and Group E during the first POD. The incidence of side effects was similar in Group CE and Group E. Conclusions: If we can reduce the concentration of fentanyl and local anesthetics in combined analgesia of epidural and cryoanalgesia, the disadvantages of each method would be overcome and would be a better method of postthoracotomy pain control.

Acquired tracheoesophageal fistula, a life threatening lesion, is rare but occurs most frequently alter prolonged mechanical ven ilation using a cuffed endotracheal tube. The mechanism of injury seems to be ischemia and inflammation of compressed trachea and esophagus by cuffed endotracheal tube. The patient was a 25 years old pregnant woman who was on prolonged mechanical ventilation for bacterial meningitis secondary to untreated otitis media. 40 days after mechanical ventilation, sudden subcutaneous empysema and pneumomediastinum ocurred and these were due to tracheoesophageal fistula. It was diagnosed with bronchoscopy and CT We performed tracheal repair with TA 60mm stapler and esophageal repair by interruted two layer suture with 410 vicryl and 510 prolene. A flap of sternocleidomastoid muscle was inserted between trachea and esophagus. Postoperative course was uneventful and the result of operation was acceptable by esophagography.

The efficacies of a supraglottic airway device (SGAD) and an endotracheal tube (ETT) in cats under general anesthesia with volume-controlled ventilation (VCV) were compared. Thirty healthy cats were randomly allocated for airway control using either an SGAD or an ETT. Five tidal volumes (6, 8, 10, 12, and 14 mL/kg) were randomly tested, and respiratory rates were adjusted to achieve a minute ventilation of 100 mL/kg/min. The dose of propofol necessary to insert the SGAD or ETT, the static respiratory pressure, leakage during VCV, and end tidal CO₂ (ETCO₂) were recorded. Dosages of propofol and static respiratory measurements for the SGAD and ETT groups were compared using a t-test. The distribution of leakages and hypercapnia (ETCO₂ > 45 mmHg) were compared using Fisher's exact test. A significance level of p < 0.05 was established. No significant difference in dose of propofol was observed between the SGAD and ETT groups (7.1 ± 1.0, 7.3 ± 1.7 mg/kg; p = 0.55). Static resistance pressure of the SGAD (22.0 ± 8.1 cmH₂O/L/sec) was significantly lower than that of the ETT (36.6 ± 12.9 cmH₂O/L/sec; p < 0.01). Of the 75 trials, leakage was more frequent when using an SGAD (8 events) than when using an ETT (1 event; p = 0.03). Hypercapnia occurred more frequently with SGAD (18 events) than with ETT (3 events; p < 0.01). Although intubation with an ETT is the gold standard in small animal anesthesia, the use of an SGAD can reduce airway resistance and the work of breathing. Nonetheless, SGAD had more dead space and the tidal volume for VCV needs adjustment.

Purpose : This scoping review was designed to identify gaps in knowledge and guide future directions for clinical nursing practices and research on oral hygiene care for endotracheally intubated patients in Korean intensive care units. Methods : We conducted a scoping review using the methodological framework proposed by Arksey and O'Malley. PubMed, CINAHL, RISS, Science On, and DBpia databases were searched. Two reviewers independently selected the studies and extracted data. A total of 445 studies were identified, of which 17 were included in the final analysis. Results : No research has been conducted from 2021 to the present. A total of 12 instruments were utilized in 13 studies to assess the effectiveness of oral hygiene care. All studies investigating the effectiveness of oral hygiene care have consistently documented that chlorhexidine has the most significant effect. The frequency and time of oral hygiene care were each examined in one study. Conclusion : A research study is necessary to develop a measurement tool for assessing the effectiveness of oral hygiene care suitable for endotracheal intubated patients in intensive care units. Interventional studies should be conducted to determine the effects of chlorhexidine and the appropriate frequency and time of oral hygiene care. Thereafter, revision of domestic evidence-based clinical practice guidelines by integrating these results will be necessary.

Massive hemoptysis is a life-threatening condition and sometimes leads to death due to airway obstruction rather than exsanguinations. In a critical hemoptysis, endotracheal intubation may be necessary to maintain adequate gas exchange and protect the unaffected side of the lung. Bronchial blockers (BBs), commonly used technique for one-lung ventilation in thoracic or cardiac surgeries, are valuable devices for protecting the airway in massive endobronchial bleeding. We report three cases intubated with BBs, Univent$^{(R)}$, in massive hemoptysis. We suggest that BBs are one of the indispensable equipments for respiratory specialized wards and intensive care units.

Purpose: The purpose of this study was to compare and analyze the effects of gargling using normal saline or essential oil on oral bacterial colonization of the subjects who did transoral endotracheal intubation for general anesthesia. Methods: A repeated measures, non-equivalent control group pretest-posttest design was used in this study. The subjects of the study included 58 people; the gargling group with normal saline (n=19); the gargling group with essential oil (n=20); and the control group (n=19). Data were collected from University hospitals in a Korean province from August 13-31, 2012. The collected data were analyzed with $X^2$-test, t-test, ANOVA and Scheff$\acute{e}$ test using SPSS 19.0. Results: Although statistically significant differences among the three groups did not appear in the change of the aerobic bacterial colony before and after the experiments, the aerobic bacterial colony of the gargling group with normal saline ($71.58{\pm}143.39$) and the group with essential oil ($6.95{\pm}332.07$) have increased less compared to the control group ($145.42{\pm}385.01$). The change of the anaerobic bacterial colony before and after the experiments, the control group was ($167.58{\pm}483.58$) and the gargling group with essential oil was ($169.70{\pm}291.60$) and increased, while the gargling group with normal saline ($-42{\pm}331.09$) reduced, but statistically significant differences have not appeared. Conclusion: These findings indicated that oral gargling with normal saline is effective in reducing anaerobic bacterial colonization.

Bronchial foreign body is not a rare disease in children and it is urgently necessary to remove this foreign body from the airway to relive life or to prevent further damages and complications. But the innate small size of airways in infants makes it difficult to access by interventional methods such as intubation or bronchoscopy and etc. Laryngeal mask airway is a new way of method of airway management which is relatively recently introduced into medical practice. It gives way to access to airways without reducing the size of airway or incresing airway pressure during procedure through it and have many other advantages compared to the previous traditional endotracheal intubation, especially in infants. We successfully removed a case of bronchial foreign body, peanut, via laryngeal mask airway during fiberoptic bronchoscopy and by this method we can avoid the unnecessary tracheostomy in this 1 year old infant.

The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice. Despite wide spread use the definitive role of the laryngeal mask airway is yet to be established. In some situations, such as after failed tracheal intubation or in oral surgery its use is controversial. There are several unresolved issues, for example the effect of the laryngeal mask on regurgitation and whether or not cricoids pressure prevents placement of mask. We review the techniques of insertion, details of misplacement, and complications associated with use of the laryngeal mask. We then attempt to clarify the role of laryngeal mask in air way management during anesthesia, discussing the advantages and disadvantages as well as indications and contraindications of its use in oral and maxillofacial surgery.

Purpose: The purpose of this study was to identify the effects of cuff pressure on postoperative sore throat. Methods: Data were collected from January 4 through May 15, 2008. Among the 60 patients, 30 patients were randomly assigned to the control group and the rest to the experimental group. Initial cuff pressure of both groups was set at 20 $cmH_2O$. The experimental group was maintained at 20 $cmH_2O$ throughout the anesthesia, while the control group was not regulated further. Sore throat was assessed at postoperative 1, 24 and 72 hours. Data were analyzed using Mann-Whitney test and Spearman's rho coefficients. Results: Cuff pressure in control group increased from 20 to 43 $cmH_2O$ within 3 hours after induction. However, the experimental group showed that there was apparently a reduced rate of sore throat at postoperative 24 hours (p = .048), and 72 hours (p = .002) than in the control group. However, no outstanding differences between both groups at postoperative 1 hour (p = .081) were detected. The correlation between cuff pressure and sore throat was statistically significant ($r_s$ = .590, p < .001). Conclusion: We conclude that maintaining cuff pressure at 20 $cmH_2O$ could be an effective means to reduce sore throat in surgical patients with inhalation anesthesia.

Chronic temporomandibular joint dislocation is defined as an acute dislocation that cannot be reduced or that recurs for more than one month. The management of dislocation depends on patient status and the duration of dislocation and ranges from conservative reduction to a surgical approach. In the present cases, a 64-year-old male was referred to our department for treatment of chronic dislocation for 6 weeks. The dislocation might be occurred by endotracheal intubation. A 70-year-old female was referred to our department with repeat right condyle dislocation after reduction of dislocation at a local clinic. When she visited for later treatment of new dentures, her condyle had been dislocated again for several weeks. In both cases, we tried to treat the dislocation with several manipulations, which were unsuccessful. Finally, chronic dislocation was successfully treated by surgical traction under general anesthesia without relapse. Surgical traction is a simple, effective option with the lowest morbidity of surgical procedures for chronic dislocation when conservative reduction is unsuccessful.
