BackgroundPostoperative urinary retention (POUR) may cause bladder dysfunction, urinary tract infection, and catheter-related complications. It is important to be aware and to be able to identify patients at risk of developing POUR. However, there has been no study that has investigated the incidence and risk factors for the development of POUR following anterior cervical spine surgery for degenerative cervical disc disease.MethodsWe included 325 patients (164 male and 161 female), who underwent anterior cervical spine surgery for cervical radiculopathy or myelopathy due to primary cervical disc herniation and/or spondylosis, in the study. We did not perform en bloc catheterization in our patients before the operation.ResultsThere were 36 patients (27 male and 9 female) that developed POUR with an overall incidence of 11.1%. The mean numbers of postoperative in-and-out catheterizations was 1.6 times and mean urine output was 717.7 mL. Thirteen out of 36 POUR patients (36%) underwent indwelling catheterization for a mean 4.3 days after catheterization for in-and-out surgery, because of persisting POUR. Seven out of 36 POUR patients (19%) were treated for voiding difficulty, urinary tract irritation, or infection. Chi-square test showed that patients who were male, had diabetes mellitus, benign prostate hypertrophy or myelopathy, or used Demerol were at higher risk of developing POUR. The mean age of POUR patients was higher than non-POUR patients (68.5 years vs. 50.8 years, p < 0.01).ConclusionsTo avoid POUR and related complications as a result of anterior cervical spine surgery for degenerative cervical disc disease, we recommend that a catheter be placed selectively before the operation in at-risk patients, the elderly in particular, male gender, diabetes mellitus, benign prostate hypertrophy, and myelopathy. We recommend that Demerol not be used for postoperative pain control.

Topical lidocaine patches at the laparoscopic port sites reduced postoperative pain, particularly postoperative wound pain after gynecological laparoscopic procedures.

BackgroundEmergence agitation (EA) in children after sevoflurane anesthesia is common. The purpose of this study was to compare the incidences of EA between ketamine and thiopental sodium induction in children underwent sevoflurane anesthesia. We also evaluated if a small dose of fentanyl could reduce the incidence of EA.MethodsThe patients who were scheduled for strabismus or entropion surgery were divided into 4 groups. The patients in Groups 1 and 2 were induced anesthesia with ketamine 1.5 mg/kg; those in Groups 3 and 4 were induced with thiopental sodium 5 mg/kg. The patients in Groups 1 and 3 received an injection of fentanyl 1.5 µg/kg, whereas the patients in Groups 2 and 4 received IV saline of the same volume. Anesthesia was maintained with sevoflurane. The recovery characteristics and EA in recovery room were assessed.ResultsThe incidence of EA was significantly higher in Groups 2 and 4 and there was no difference between Groups 2 and 4. Group 2 had almost an eleven-fold higher risk of developing EA than did Group 1, and the incidence of EA in Group 4 was sixty-nine-fold higher than that of Group 1. The risk factor for EA was only the kind of medication. Preoperative anxiety had no significant correlation with EA.ConclusionsThe incidence of EA after sevoflurane anesthesia is similar between ketamine and thiopental sodium anesthetic induction in children undergoing pediatric ophthalmic surgery. Also, the addition of a small dose of fentanyl after anesthetic induction decreases the incidence of EA.

An aneurysm of the innominate artery could compress the tracheal lumen, and this requires special care. Intubation without intensive monitoring and antihypertensive agents could aggravate the hypercapnia and completely rupture the aneurysm. There are few reports on the airway management of tracheal compression that's caused by an innominate artery aneurysm. We report here on a patient who had a severe hypercapnia after endotracheal intubation above the stenotic area of the tracheal compression, which was caused by an artery aneurysm. Permissive hypercapnia was inadvertently enforced without our knowledge, but the patient recovered without any neurologic problems.

Rationale:Arthroscopic shoulder surgery (ASS) is a low mortality and morbidity procedure, but anesthetic complications are reported. There have been no reports of combined chest wall swelling and pneumothorax after ASS.Patient concerns:The patient's right lung was severely collapsed and the mediastinum was deviated after ASS.Diagnosis:Pneumothorax on right chest.Interventions:A chest tube was inserted and oxygen therapy was performed.Outcomes:The patient was discharged uneventfully.Lessons:Elective ASS has low mortality and morbidity rates, but we should be more concerned over the complications after ASS.

ObjectiveTo determine the correlation between anatomical features of the upper airway (evaluated via computed tomography imaging) and the ease of light wand-assisted endotracheal intubation in patients undergoing ear, nose and throat surgery under general anaesthesia.MethodsMallampati class, laryngoscopic grade, thyromental distance, neck circumference, body mass index, mouth opening and upper lip bite class were assessed. Epiglottis length and angle, tongue size and narrowest pharyngeal distance were determined using computed tomography imaging. Intubation success rate, time to successful intubation (intubating time) and postoperative throat symptoms were documented.ResultsOf 152 patients, 148 (97.4%) were successfully intubated on the first attempt (mean intubating time 11.5 ± 6.7 s). Intubating time was positively correlated with laryngoscopic grade and body mass index in both male and female patients, and Mallampati class and neck circumference in male patients. Epiglottis length was positively correlated with intubating time.ConclusionsEase of intubation was influenced by epiglottis length. Radiological evaluation may be useful for preoperative assessment of patients undergoing endotracheal intubation with light wand.

A 74-year-old male patient receiving ventilatory support due to aspiration pneumonia developed bilateral pneumothorax, pneumopericardium, pneumomediastinum, pneumo-retroperitoneum, and subcutaneous emphysema, after manual ventilation while being transferred from the intensive care unit (ICU) to the operating room (OR). These complications were assumed to be secondary to inappropriate manual ventilation of the intubated patient. In addition, it is likely that the possible migration of an already marginally acceptable endotracheal tube (ETT) position during transport was the cause of these complications. Finally, aggravation of a latent pneumothorax might have contributed to these complications.
