ABSTRACT
BACKGROUND: Venous thromboembolism (VTE) is a serious complication that arises after major abdominal surgery. VTE poses risks of negative outcomes and health care burden. The literature on the cost of VTE in Japanese surgical patients, however, is scarce. OBJECTIVE: This study was conducted to investigate the economic consequences of VTE in Japanese patients with major abdominal surgery, using a hospital claims database. METHODS: This is a retrospective, matched cohort study. Patients who had a VTE event up to 90 days after their first major abdominal surgery and initiated warfarin or heparin within 1 day of VTE diagnosis with continued treatment for more than 4 weeks were matched with controls for surgery type, hospital, and date of surgery ± 6 months in a 1:2 scheme. The primary outcome was 90-day costs associated with major abdominal surgery. The secondary outcomes were 6-month total costs, average length of initial inpatient stay, and cost of initial inpatient stay. RESULTS: The 90-day cumulative incidence of VTE was 4.89%. The development of a VTE event in patients undergoing major abdominal surgery resulted in a 1.5-fold increase in the length of hospitalization and a 2.8-fold increase in total costs 90 days after the surgery. Total costs further increased to 3.4-fold at 6 months. Overall, costs incurred in patients with VTE are on average much higher than in patients without VTE throughout 6-month postsurgery. CONCLUSIONS: The preventive care for VTE using more effective prophylactic treatment is recommended to reduce the economic burden associated with major abdominal surgery.
ABSTRACT
We report three cases of continuous wound infiltration (CWI) for postoperative analgesia in upper abdominal surgery using the multi-holed epidural catheter. Ropivacaine 0.2% at a rate of 8 ml x hr(-1) was administered through the catheters after surgery. Intravenous-patient controlled analgesia was used as a rescue. The postoperative pain was well controlled, and all patients could walk the next day after surgery. The consumption of rescue morphine was little and no side effect of morphine was observed. CWI is an easy procedure and is indicated in the patients with hemostatic abnormality and a difficulty in the epidural anesthesia. CWI was an effective technique for postoperative pain control in the upper abdominal surgery patients.

PURPOSE: In many countries, patients are generally allowed to have clear fluids until 2-3 h before surgery. In Japan, long preoperative fasting is still common practice. To shorten the preoperative fasting period in Japan, we tested the safety and efficacy of oral rehydration therapy until 2 h before surgery. METHODS: Three hundred low-risk patients scheduled for morning surgery in six university-affiliated hospitals were randomly assigned to an oral rehydration solution (ORS) group or to a fasting group. Patients in the ORS group consumed up to 1,000 ml of ORS containing balanced glucose and electrolytes: 500 ml between 2100 the night before surgery and the time they woke up the next morning and 500 ml during the morning of surgery until 2 h before surgery. Patients in the fasting group started fasting at 2100 the night before surgery. Primary endpoints were gastric fluid volume and pH immediately after anesthesia induction. Several physiological measures of hydration and electrolytes including the fractional excretion of sodium (FENa) and the fractional excretion of urea nitrogen (FEUN) were also evaluated. RESULTS: Mean (SD) gastric fluid volume immediately after anesthesia induction was 15.1 (14.0) ml in the ORS group and 17.5 (23.2) ml in the fasting group (P = 0.30). The mean difference between the ORS group and fasting group was -2.5 ml. The 95% confidence interval ranged from -7.1 to +2.2 ml and did not include the noninferior limit of +8 ml. Mean (SD) gastric fluid pH was 2.1 (1.9) in the ORS group and 2.2 (2.0) in the fasting group (P = 0.59). In the ORS group, mean FENa and FEUN immediately after anesthesia induction were both significantly greater than those in the fasting group (P < 0.001 for both variables). The ORS group reported they had been less thirsty and hungry before surgery (P < 0.001, 0.01). CONCLUSIONS: Oral rehydration therapy until 2 h before surgery is safe and feasible in the low-risk Japanese surgical population. Physicians are encouraged to use this practice to maintain the amount of water in the body and electrolytes and to improve the patient's comfort.

We report a case of unexpected difficult intubation in a patient with an asymptomatic congenital laryngeal web. A 44-year-old female with left ovarian tumor and endometrial polyp was scheduled for abdominal hysterectomy and left salpingo-oophorectomy under general anesthesia. With aid of laryngoscopy using Macintosh laryngoscope, we attempted to place a tracheal tube (ID 7.5 mm and 7.0 mm), but could not perform instrumentation because of the resistance against the tube just under the vocal cord. We visualized the glottic opening through the Airway Scope and found a membranous lesion at the ventral side of the glottis, diagnosing a congenital laryngeal web. We finally could insert a tracheal tube of ID 6.5 mm into the dorsal side of the glottis. Airway Scope may be a useful device for unexpected difficult tracheal intubation.

BACKGROUND: The aim of the present study was to compare the percent of glottic opening score between middle-size (#3) and large-size (#4) handles during laryngoscopy using the GlideScope videolaryngoscope (GVL) in Japanese women. METHODS: In 80 Japanese women receiving general anesthesia for surgical procedures, laryngoscopy was performed using GVL #3 handle and GVL #4 handle. We compared the percentage of glottic opening score between the two handles on each patient. RESULTS: The percentage of glottic opening score was higher with GVL #3 handle than with GVL #4 handle [66 +/- 28% (mean +/- SD), vs. 53 +/- 34%, P < 0.05). CONCLUSIONS: The use of GVL #3 handle is recommended for tracheal intubation for Japanese women.

DESIGN: A prospective, randomized, open study. The regional technique used was not blinded. SETTING: A university teaching hospital. PARTICIPANTS: Forty-eight patients undergoing video-assisted thoracoscopic surgery (VATS) for tumor resection. INTERVENTIONS: Patients received either continuous extrapleural block or continuous epidural block using ropivacaine for a period of 60 hours after surgery. MEASUREMENTS AND MAIN RESULTS: To evaluate postoperative pain control, the primary and secondary endpoints were the visual analog scale (VAS) on movement and the amount of rescue analgesia, respectively. There were no significant differences between the extrapleural and epidural block groups with regard to VAS at rest and during movement assessed at 4, 12, 24, 36, and 48 hours after surgery, dosage of intravenous morphine (extrapleural: 12.9 ± 11.3, epidural: 10.2 ± 6.9 mg), supplemental nonsteroidal anti-inflammatory drugs, incidence of postoperative nausea and vomiting (extrapleural: 12/20, epidural: 11/20), postoperative ambulation (extrapleural: 18 at postoperative day [POD] 1 and 20 at POD 2, epidural: 19 at POD 1 and 20 at POD 2) and hospital stay after surgery (extrapleural: 12.7 ± 6.3, epidural: 12.6 ± 4.7 days). CONCLUSIONS: Although this study did not show the superiority of continuous extrapleural block relative to continuous epidural in VATS patients, the results suggest that both methods provided effective analgesia with a relatively small dose of rescue morphine. Although the analgesic effects of these techniques were comparable, extrapleural block has the advantage of safety and precise placement of the catheter and can be considered an alternative to epidural block in VATS patients.

The patient is a 61-year-old man who had previously undergone an extended thymectomy for myasthenia gravis. Endoscopic examination during a routine follow-up visit revealed early gastric cancer in the proximal portion of the stomach. To undergo resection the patient received general and epidural anesthesia. The conditions were unfavorable for laparoscopic-assisted surgery because he had a body mass index of 33 and muscle relaxants could not be used. Pneumoperitoneum was induced with carbon dioxide, and the abdominal wall was lifted. An adequate working space was secured in the upper abdomen and proximal gastrectomy was successfully performed.

Limb girdle muscular dystrophy, a chronic progressive muscular atrophic disease, leads to high sensitivity to depolarizing and non-depolarizing neuromuscular blocking agents. We report the successful use of the sugammadex in a patient with limb girdle muscular dystrophy (dysferlinopathy, Miyoshi distal myopathy) to reverse rocuronium-induced neuromuscular block. After neuromuscular recovery to a train-of-four ratio = 43%, we administered 3.2 mg x kg(-1) of sugammadex (200 mg) intravenously, reversing neuromuscular blockade to a train-of-four ratio = 95% within 3 min. Sugammadex can be used to reverse rocuronium-induced neuromuscular blockade in patients with limb girdle muscular dystrophy.

A 37-year-old man with Kniest dysplasia and thoracic myelopathy was scheduled for T3-12 laminectomy. Kniest dysplasia is a severe chondrodysplasia characterized by short trunk and limbs. Awake fiberoptic intubation was attempted to prevent airway obstruction because we had predicted his difficult airway. During fiberoptic tracheal intubation, we easily succeeded in the insertion of the fiberscope itself into the trachea, but were not able to insert the tip of a reinforced tube into the trachea, because the tip of the reinforced tube impinged on laryngeal structures. We succeeded in placing the Parker Flex-Tip tracheal tube into the trachea. We considered that the Parker Flex-Tip tube, having a tip that reduces the gap between the fiberscope and the inside of the tube, resulted in success of the passage of the tube into the trachea during fiberoptic intubation.

BACKGROUND: GlideScope videolaryngoscope (GVL) is a novel indirect laryngogoscope for tracheal intubation. Both mid-size and large blades of the GVL are available for adult patients. The distortion of the anterior airway anatomy and cervical spine motion using the mid-size GVL is unknown. We compare the degree of anterior airway distortion and cervical spine movement during the use of the mid-size GVL compared with the large GVL. METHODS: Twenty patients requiring general anesthesia and tracheal intubation were studied. Each patient underwent laryngoscopy with both mid-size and large GVLs. During each laryngoscopy, a radiograph for the lateral view of the head and neck was taken when the best view of the larynx was obtained. Based on the radiographs, independent radiologists evaluated anterior airway movement and cervical spine movement. RESULTS: The tip of the mid-size GVL was anteriorly positioned during laryngoscopy, compared with large GVL. The distance between epiglottis and posterior laryngeal wall was longer with the mid-size GVL than with the large GVL. Both the mid-size and large GVL caused a significant anterior movement in the cervical spine during laryngoscope. The difference in the movement in the atlas and C2 was small, but statistically significant. No difference was found in the anterior movement with C3 and C4. During laryngoscopy, cervical spinal extension occurred with both GVLs, while there was no difference in the cervical spinal extension between the mid-size and large GVL. CONCLUSIONS: The tip of the mid-size GVL during laryngoscopy is anteriorly positioned and the distortion of the anterior airway was greater with the mid-size GVL than with the large GVL.

BACKGROUND: The aim of the present study was to evaluate the suitability of Airtraq optical laryngoscope for the tracheal intubation in children. METHODS: Endotracheal intubation was performed using the Airtraq optical laryngoscope in 100 pediatric patients undergoing general anesthesia. The time to complete tracheal intubation and optimizing procedures were recorded. RESULTS: The Airtraq optical laryngoscope allowed visualization of the glottis and successful intubation in the 100 patients, including three patients with difficult airway. Utilization of a gum elastic bougie was helpful to introduce a tube tip to the trachea. CONCLUSIONS: The Airtraq optical laryngoscope might be an alternative apparatus for endotracheal intubation in pediatric patients.

A Forestier's disease patient was scheduled for endoscopic mucosal resection under general anesthesia, because of his hypoxic episode during gastric endoscopy. Endotracheal intubation was planned while awake, because he was suspected as a case of difficult airway. By using AWS, we could easily confirm his larynx and aditus of trachea in spite of his narrow pharynx caused by Forestier's disease. The procedure was successful with no complications. AWS seems to be a useful device for endotracheal intubation in Forestier's disease.

We report a successful use of pediatric Airtraq optical laryngoscope in a pediatric patient with Robin sequence. Robin sequence accompanies a characteristic facies and its clinical presentation is marked by micrognathia, retrognathia, glossoptosis, and respiratory obstruction. A 1-year-5 month-old boy with Robin sequence was scheduled for palate repair under general anesthesia. After anesthetic induction with thiopental and neuromuscular paralysis with rocuronium, initial laryngeal view with the conventional Macintosh laryngoscope was Cormack-Lehane grade II due to restricted mouth opening and micrognathia. The Airtraq Pedi provided the glottic view with Cormack-Lehane grade I and a preformed tracheal tube (ID 4 mm) was placed correctly into the trachea through the built-in tube channel. We conclude that the pediatric Airtraq has potential advantages over conventional direct laryngoscopy in children with difficult airway.

Helmet is a new device of non-invasive continuous positive airway pressure (CPAP). Few cases have been described about usage of the helmet in children. We describe successful treatment of a child with respiratory distress using the helmet-delivered non-invasive CPAP. A 2-month-old male infant (3.1 kg) with multiple anomalies (cardiovascular, facial, and vertebral) developed respiratory distress after extubation. The helmet was well tolerated regardless of facial anomaly. Helmet CPAP started at initial settings of CPAP 8 cm H2O and FI(O2) 0.7, improved oxygenation. Pa(O2)/FI(O2) ratio increased from 106 to 316, and chest X-rays showed a marked improvement (15 hour after NPPV initiation). The helmet offers important advantage: the possibility of fitting to any children, regardless of any facial or external anomalies.

BACKGROUND: We compared the performance of GlideScope videolaryngoscope with that of the conventional Macintosh laryngoscope for nasotracheal intubation by non-anesthesia residents. METHODS: Forty patients requiring nasal endotracheal intubation for surgical convenience were allocated to intubation with the GlideScope videolaryngoscope or Macintosh laryngoscope. Each intubation was performed by non-anesthesia residents. RESULTS: The time to secure the airway was shorter with GlideScope laryngoscopy than with the Macintosh laryngoscopy. Magill forceps were not needed for any patient during GlideScope videolaryngoscopy, while Macintosh laryngoscopy required Magill forceps utilization for 75% of the patients. CONCLUSIONS: The unobstructed view of the glottic opening on the video monitor helped the laryngoscopist performing the nasal endotracheal intubation while an assistant provided laryngeal manipulation to improve the coordinated effort. GlideScope seems to facilitate nasotracheal intubation for individuals training in airway management.

BACKGROUND: To evaluate obstetric and anesthetic problems relating to cesarean delivery, we investigated parturients who had undergone cesarean section at the Center for Perinatal and Neonatal Medicine in Jichi Medical University Hospital. METHODS: Obstetric and anesthetic data were gathered from January 2007 to December 2007 for all cesarean sections. RESULTS: In all, 607 parturients received cesarean section during the period. Of the 607 cesarean deliveries, 308 were performed in elective condition, and 299 were done in emergency situation. Of the 299 emergencies, 125 underwent cesarean section at nights and/or holidays. Population risk included maternal age (age >35 year, 33.1%), preterm birth (31.5%), and obesity (BMI >35 kg x m(-2), 3.3%). Complicated pregnancy included multifetal pregnancies (15.2%) and placenta previa (12.5%). CONCLUSIONS: At the center for perinatal and neonatal medicine, population risk is increasing because of increases in maternal age, obesity, placenta previa, and rates of multifetal pregnancies.

We report a case of inadvertent arterial misplacement of a large-caliber cannula during jugular vein catheterization. A tip of a 9F cannula was inadvertently placed into the brachiocephalic trunk via the subclavian artery. The arterial trauma was managed by cannula removal and external compression without secondary traumas. Our case emphasizes that the excursion of the subclavian artery is associated with a significant risk of trauma on the subclavian artery during jugular vein catheterization.

BACKGROUND: The Japanese Society of Anesthesiologists (JSA) has maintained records of the annual incidence and characteristics of perioperative pulmonary thromboembolism (perioperative PTE) since 2002. The aim of this paper was to provide recent results of the JSA annual study conducted in 2008, and to determine the current factors that tend to prevent perioperative venous thromboembolism (VTE) in Japan. METHODS: A comprehensive questionnaire designed by the JSA PTE working group was mailed to all institutions certified as teaching hospitals by JSA. The data tics of patients with perioperative PTE, such as types of diseases and surgeries, age, sex, methods used for the prevention of VTE (in some cases), and prognosis of perioperative PTE. RESULTS: The rate of effective responses was 56.1% (634/1116), and 1,177,626 surgeries were registered during the study period. There were 324 patients who were reported to have had PTE, and the incidence was 2.75 per 10,000 surgeries. The incidence of perioperative PTE in 2008 did not change significantly from that in 2005-07. The surgeries that most commonly resulted in perioperative PTE were limb and/or hip joint surgery (5.71 per 10,000 surgeries), craniotomy (4.64 per 10,000), and thoracotomy with laparotomy (3.46 per 10,000 surgeries). The mortality rate of perioperative PTE in 2008 was found to have significantly decreased from that in 2005-07 (15.6% vs. 22.4%; P = 0.01). Further, the rate of patients who received anticoagulant drugs in 2008 was significantly higher than that in 2005-07 (17.6% vs. 10.8%; P = 0.0018). Individual guidelines for the prevention of perioperative VTE were adopted in 55.4% of the training institutions. CONCLUSIONS: The increase in the percentage of patients who received anticoagulant drugs around the time of the operation, and the decreased mortality of patients with perioperative PTE suggested that the prophylaxis for perioperative VTE with anticoagulant drugs reduces perioperative mortality.

BACKGROUND: The Airtraq optical laryngoscope allows visualization of the glottis through a non-line-of sight view. The aim of the present study was to evaluate the suitability of this device for the tracheal intubation of surgical patients. METHODS: The Airtraq was used for the endotracheal intubation in 300 surgical patients. RESULTS: The Airtraq optical laryngoscope allowed visualization of the glottis and successful intubation in 298 out of 300 patients. Endotracheal intubations were easily performed both with normal and difficult airways. CONCLUSIONS: The Airtraq optical laryngoscope consistently permitted a better intubation environment. With its potential advantages, the Airtraq optical laryngoscope could be an effective aid to airway management in surgical patients.

PURPOSE: A non-line-of-sight view is expected to cause less movement of the anterior airway anatomy and cervical spine during laryngeal visualization. Reduced distortion of anterior airway anatomy during laryngoscopy with the GlideScope videolaryngoscope (GVL), compared with the Macintosh laryngoscope, could explain the relatively easier nasotracheal intubation with the GVL. The purpose of this radiographic study was to compare the degree of anterior airway distortion and cervical spine movement during laryngoscopy with the GVL and the conventional Macintosh laryngoscope. METHODS: Twenty patients requiring general anesthesia and tracheal intubation were studied. Each patient underwent laryngoscopy using the first-generation GVL and a direct laryngoscope with a Macintosh blade. During each laryngoscopy, a radiograph was taken when the best view of the larynx was obtained. Independent radiologists with subspeciality training in musculoskeletal imaging evaluated anterior airway distortion and cervical spine movement. RESULTS: The distance between the epiglottis and the posterior pharyngeal wall during the GlideScope procedure was 21% less than that during the Macintosh laryngoscopy (P < 0.05). Anterior deviations of the vertebral bodies from baseline were 27, 32, 36, and 39% less at the atlas, C2, C3, and C4 vertebrae, respectively, during the GlideScope procedure than those measured during Macintosh laryngoscopy (P < 0.01). Cervical extension between the occiput and C4 during the GlideScope procedure was 23% less than that during Macintosh laryngoscopy (P < 0.05). CONCLUSION: Both anterior airway distortion and cervical spine movement during laryngeal visualization were less with the GVL than with the Macintosh laryngoscope.
