Abstract PDF: Delirium is described as a manifestation of acute brain injury and recognized as one of the most common complications in intensive care unit (ICU) patients. Although the causes of delirium vary widely among patients, delirium increases the risk of longer ICU and hospital length of stay, death, cost of care, and post-ICU cognitive impairment. Prevention and early detection are therefore crucial. However, the clinical approach toward delirium is not sufficiently aggressive, despite the condition’s high incidence and prevalence in the ICU setting. While the underlying pathophysiology of delirium is not fully understood, many risk factors have been suggested. As a way to improve delirium-related clinical outcome, high-risk patients can be identified. A valid and reliable bedside screening tool is also needed to detect the symptoms of delirium early. Delirium is commonly treated with medications, and haloperidol and atypical antipsychotics are commonly used as standard treatment options for ICU patients although their efficacy and safety have not been established. The approaches for the treatment of delirium should focus on identifying the underlying causes and reducing modifiable risk factors to promote early mobilization.

Abstract PDF: Whole lung lavage (WLL) is a challenging procedure; because lavage fluid may perturb the respiratory and hemodynamic systems. We observed severe airway obstruction and flattening arterial pressure wave during WLL for treatment of pulmonary alveolar proteinosis. The aim of this case report is to discuss the anesthetic requirement in order to prevent bronchospasm during WLL. Furthermore, we discuss the potential of lavage fluid to cause airway obstruction and decrease cardiac outflow through the mass effect.

Abstract PDF

BACKGROUND
Robotic radical prostatectomy is performed in elderly patients and requires extreme changes in the patient's position and is often associated with a long surgery time. This study reviewed the pulmonary complications occurring after a robotic radical prostatectomy and analyzed the potential risk factors.
METHODS
The medical records of all patients who had undergone robotic radical prostatectomy at our institution were reviewed. Among the 80 total patients, 58 were capable of spontaneous respiration at the end of surgery (Group I), whereas 22 patients required assisted ventilation (Group II). A comparison between the two groups was made in terms of the demographic characteristics, coexisting diseases, anesthesia and operation time, amount of intraoperative blood loss and transfused blood products.
RESULTS
The mean age of the patients was 67.2 +/- 7.3 years. The mean operation time was 384.1 +/- 203.4 min (range, 195-1,180 min). The anesthesia and operation time, amount of intraoperative blood loss and number of transfused patients were all significantly higher in Group II. Univariate analysis revealed age, body mass index, intraoperative blood loss and transfusion, anesthesia and operation time to be related to postoperative respiratory insufficiency. Multivariate analysis revealed intraoperative transfusion and operation time to be predictive risk factors.
CONCLUSIONS
Prolonged laparoscopic surgery in a steep Trendelenburg position has a high likelihood of postoperative respiratory insufficiency, with the intraoperative transfusion and a longer operation time being possible contributing factors.

Abstract PDF: BACKGROUND
The blood components of priming solution for cardiopulmonary bypass (CPB) may have opposite roles for tissue perfusion, which are the activation of inflammatory reaction and the improvement of oxygen carrying capacity. This study is aimed to investigate the effect of blood transfusion of priming solution on inflammatory response and tissue perfusion. METHODS: Twenty mongrel dogs randomly allocated and received hypothermic CPB with blood- containing (H group, n=10), or non-hemic (NH group, n=10) priming solution. Gastric intramucosal CO2 concentration (PrCO2), intramucosal pH (pHi), interleukin-8 (IL-8), blood gas and hemodynamic parameters were measured at 1) before CPB, 2) 1 hour during CPB, 3) the end of CPB, 4) 2 hours after CPB, 5) 4 hours after CPB. The ratio of wet to dried lung weight was measured. Statistical verification was performed using repeated measures ANOVA and unpaired t-test.
RESULTS
PrCO2 increased and pHi decreased during the study without significant difference between the groups. IL-8 increased in both groups and IL-8 of H group increased higher than that of NH group during the study. The difference between PaCO2 and end-tidal CO2 of NH group was higher than that of H group at 4 hours after CPB. The ratio of wet to dried lung weight was not significantly different between the groups. CONCLUSIONS: We conclude that the allogenic blood in priming solution aggravates the CPB- induced inflammatory reaction, however, the CPB-induced impairment of gastric mucosal perfusion and the pulmonary edema are not significantly affected, compared to non-hemic solution.

Abstract PDF: Usually FEV1 lower than 1 liter is considered as a contraindication to pneumonectomy. Therefore sometimes, the curative operations of the resectable lung cancer can not be performed in case of poor pulmonary functions. The usual criteria on the performance of pneumonectomy on high risk patients based on the preoperative assessment of pulmonary function may not predict the operative outcome with accuracy in the postoperative period. Nowadays, there are some arguing points about applying the values of preoperative PFTs to pulmonary resection surgery. We performed a right pneumonectomy for stage IIIb lung cancer in a patient with poor lung function test; FVC 2.17 L, FEV1 0.97 L, FEV1/FVC 44%, FEF 25~75% 0.42 L/sec, MVV 28 L/min, TLC 5.18 L, RV 2.99, DLCO 13.46. After the temporary ligation of right main pulmonary artery during 30 minutes, arterial blood gas and percutaneous oxygen saturation with the controlled ventilation with room air (FiO2=0.21) confirmed the hemodynamic and oxygenation stabilities, twice. After successful surgery, the patient was tolerated for 4 months. And the follow up PFTs at postoperative 3 months and 18 days showed as follows; FVC 1.20 L, FEV1 0.63 L, FEV1/FVC 53%, FEF 25~75% 0.31 L/sec, MVV 25 L/min, TLC 3.80 L, RV 2.33 L, DLCO 8.04. Through the intraoperative re-evaluation of pulmonary function in a patient with poor preoperative PFTs,had been conventionally considered as a contraindication to pneumonectomy, we report a successful surgery and anesthetic management with the literatures reviewed.
