Objective: Postoperative delirium (POD) is characterized by an acute change in cognitive function and can result in longer hospital stays, higher morbidity rates, and more frequent discharges to long-term care facilities. In this study, we investigated the incidence and risk factors of POD in 224 patients older than 70 years of age, who had undergone a neurosurgical operation in the last two years. Methods: Data related to preoperative factors (male gender, >70 years, previous dementia or delirium, alcohol abuse, serum levels of sodium, potassium and glucose, and co-morbidities), perioperative factors (type of surgery and anesthesia, and duration of surgery) and postoperative data (length of stay in recovery room, severity of pain and use of opioid analgesics) were retrospectively collected and statistically analyzed. Results: POD appeared in 48 patients (21.4%) by postoperative day 3. When we excluded 26 patients with previous dementia or delirium, 17 spontaneously recovered by postoperative day 14, while 5 patients recovered by postoperative 2 months with medication, among 22 patients with newly developed POD. The univariate risk factors for POD included previously dementic or delirious patients, abnormal preoperative serum glucose level, pre-existent diabetes, the use of local anesthesia for the operation, longer operation time (>3.2 hr) or recovery room stay (>90 mini, and severe pain (VAS>6.8) requiring opioid treatment (p<0.05). Backward regression analysis revealed that previously dementic patients with diabetes, the operation being performed under local anesthesia, and severe postoperative pain treated with opioids were independent risk factors for POD. Conclusion: Our study shows that control of blood glucose levels and management of pain during local anesthesia and in the immediate postoperative period can reduce unexpected POD and help preventing unexpected medicolegal problems and economic burdens.

Objective: The aim of this study was to compare the electrodiagnostic outcomes of carpal tunnel release in patients with and without diabetes with carpal tunnel syndrome (CTS), and to evaluate the effect of diabetes mellitus (DM) on electrodiagnostic outcomes. Method: We conducted a retrospective analysis of 67 patients with electro-diagnostic evidence of CTS. Patients were classified into two groups according to the presence of DM. Both groups were evaluated using nerve conduction studies preoperatively and 3 weeks and 3 months postoperatively. Results: There were no statistical differences in any of the electrodiagnostic parameters between groups 3 weeks postoperatively. However, there were statistical differences in the amplitude and the latency of compound muscle action potential, and sensory nerve conduction velocity 3 months postoperatively. Conclusion: Patients with DM did not show a significantly different outcome 3 weeks after surgery but showed a worse electrodiagnostic outcome 3 months after surgery than those without DM.

Purpose: To determine the incidence and risk factors of postoperative infection after cranioplasty in patients with traumatic brain injury (TBI). Methods: Data of 289 adult patients who underwent cranioplasty after TBI at a single regional trauma center between year 2018 and 2021 were reviewed retrospectively. Patient characteristics and various procedural variables, such as interval between craniectomy and cranioplasty, estimated blood loss, laterality and materials of the bone flap, and duration and classification of perioperative antibiotics usage were analyzed. Results: Postoperative infection occurred in 17 patients (5.9%). Onset time of infectious symptom ranged from 9 days to 174 days (median, 24 days) after cranioplasty. The most common cultured organism was Staphylococcus aureus (47.1%), followed by Klebsiella pneumoniae (17.6%) and Enterococcus faecalis (17.6%). Patients with postoperative infection were more likely to have diabetes (odds ratio [OR], 6.96; 95% confidence interval [CI], 1.92-25.21; P=0.003), lower body mass index (OR, 0.81; 95% CI, 0.66-0.98; P=0.029), and shorter duration of perioperative antibiotics (OR, 0.83; 95% CI, 0.71-0.98; P=0.026). Conclusions: For TBI patients with diabetes, poor nutritional status should be managed cautiously for increased risk of infection after cranioplasty. Further studies and discussions are needed to determine an appropriate antibiotics protocol in cranioplasty.

Background Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. Studies have shown that results of CTS surgery are poorer in patients with diabetes. In this study, the effect of platelet-rich plasma (PRP) on nerve regeneration was investigated through clinical and electromyographic findings in patients with diabetes who underwent CTS surgery. Methods A retrospective analysis of 20 patients with diabetes who had surgically decompressed CTS was conducted. Patients were divided into two groups. The study group received PRP treatment following surgery. The control group did not receive any treatment. Patients were assessed using electromyography and the Boston Carpal Tunnel Syndrome Questionnaire preoperatively as well as postoperatively at 3-month, 6-month, and 1-year follow-ups visits. Results There was a decrease in complaints and an improvement in sensory and motor examinations in both groups. The Boston Carpal Tunnel Syndrome Questionnaire scores did not show any statistically significant differences between the two groups. However, electromyographic findings showed that there were statistical differences between preoperative and postoperative (3 months, 6 months, and 1 year) results in both groups. When the two groups were compared using preoperative and postoperative (3 months, 6 months, and 1 year) electromyographic values, no statistically significant differences were seen. Conclusion Single injections of PRP did not have a significant impact on median nerve regeneration following CTS surgery in patients with diabetes. The effectiveness of multiple PRP injections can be investigated in patients with diabetes in future studies.

We carried out this study to investigate differences of physiological variables between patients with (DM group) and without type II diabetes mellitus (Non-DM group) undergoing off-pump coronary artery bypass grafting (OPCABG). Postoperative $Mg^{++}$ and $Ca^{++}$ levels were lower, whereas $Na^+$ level was higher in DM group than those in Non-DM group. ICU (intensive care unit) stay time in DM group was longer than that of Non-DM group. Postoperative platelet counts tended to decrease, whereas C-reactive protein (CRP) and cardiac troponin-I (cTNI) levels tended to increase in DM group compared with Non-DM group. Postoperative albumin level was lower, while blood urea nitrogen (BUN) and creatinine levels were greater in DM group than those in Non-DM group. DM group had higher incidence of post-operative arrhythmias than Non-DM group. These results reveal that type II DM patients undergoing OPCAB may have higher incidences of postoperative hypomagnesemia, hypocalcemia and arrhythmias, and increases of CRP, cTNI, BUN, and creatinine levels than in Non-DM patients undergoing OPCAB. The perioperative check and control (supplement) of $Mg^{++}$ levels should be considered in cardiovascular surgery combined with DM.

Purpose Pulmonary complications continue to be the major cause of morbidity and mortality after esophageal resection. The aim of this study was to compare and analyze retrospectively the factors which effect for postoperative pulmonary complications in patients who underwent curative resection for esophageal cancer. Material and Method A total of 118 patients were enrolled in the study from January 1994 to March 2009, and patients with previous neoadjuvant chemotherapy or radiotherapy were excluded. Of the total 118 patients, 27 patients developed pulmonary complications within 30 days of their operation. the factors which effect for postoperative pulmonary complications were compared and analyzed. Results There were 7 patients in-hospital deaths. 51 patients (43.2%) developed complications, and of them, the most common complication was pulmonary complication and occurred in 27 patients (22.9%). In univariate analysis, diabetes mellitus, cervical anastomosis through the retrosternal route, old age and poor lung function were risk factors contributing to postoperative pulmonary complications (p<0.05). In multivariate analysis, statistically significant factor was old age (65 years or older). Conclusion Clinical factor for the pulmonary complications after esophagectomy of esophageal cancer was significantly associated with diabetes mellitus, cervical anastomosis through the retrosternal route, old age (65 years or older) and poor lung function (FEV1<80%). Of these, old age was the most significant factor.

Objective : Rehemorrhage is the most severe complication of postoperative patients with spontaneous intracerebral hemorrhage. The aim of the present study was to assess independent predictors of rehemorrhage and find the possibility of preventing rehemorrhage in postoperative patients with spontaneous intracerebral hemorrhage (sICH). Methods : Medical records of 263 postoperative patients with sICH from our Hospital were reviewed. The relationships between rehemorrhage and parameters were examined by univariate and multivariate analyses. The parameters include time from onset to surgery, hematologic paremeters, neuroimaging characteristics, level and variability of systolic blood pressure, medical histories, operation duration, and blood loss. In addition, relationship between rehemorrhage and clinical outcome were analyzed by using multivariate analyses. Results : Thirty-five (13.31%) patients experienced rehemorrhage after operation. Multivariate analyses indicated that the following factors were independently associated with rehemorrhage : history of diabetes mellitus (odds ratio [OR], 2.717; 95% confidence interval [CI], 1.005-7.346; p=0.049), and midline shift (for every 1 mm increase, OR, 1.117; 95% CI, 1.029-1.214; p=0.009). Rehemorrhage was an independent risk factor of poor functional outcome (OR, 3.334; 95% CI, 1.094-10.155; p=0.034). Conclusion : Our finding revealed that history of diabetes mellitus and admission midline shift were possibly associated with rehemorrhage in postoperative patients with sICH.

Objective : The purpose of this study is to identify the relationship between asymptomatic urinary tract infection (aUTI) and postoperative spine infection. Methods : A retrospective review was done in 355 women more than 65 years old who had undergone laminectomy and/or discectomy, and spinal fusion, between January 2004 and December 2008. Previously postulated risk factors (i.e., instrumentation, diabetes, prior corticosteroid therapy, previous spinal surgery, and smoking) were investigated. Furthermore, we added aUTI that was not previously considered. Results : Among 355 patients, 42 met the criteria for aUTI (Bacteriuria ${\geq}\;10^5\;CFU/mL$ and no associated symptoms). A postoperative spine infection was evident in 15 of 355 patients. Of the previously described risk factors, multi-levels (p<0.05), instrumentation (p<0.05) and diabetes (p<0.05) were proven risk factors, whereas aUTI (p>0.05) was not statistically significant. However, aUTI with Foley catheterization was statistically significant when Foley catheterization was added as a variable to the all existing risk factors. Conclusion : aUTI is not rare in elderly women admitted to the hospital for lumbar spine surgery. The results of this study suggest that aUTI with Foley catheterization may be considered a risk factor for postoperative spine infection in elderly women. Therefore, we would consider treating aUTI before operating on elderly women who will need Foley catheterization.

심장 박동상태에서 시행하는 관상동맥우회술(off-pump CABG)은 심폐체외순환하에서 시행하는 관상동맥우회술(on-pump CABG)에 비해 수술 후 유병률을 줄일 수 있는 방법으로 보고되고 있다. 저자들은 특히 수술 후 합병증의 발생 가능성이 높은 당뇨환자에 있어서 off-pump CABG와 on-pump CABG의 임상 결과를 비교하여 off-pump CABG가 당뇨환자의 유병률에 미치는 영향을 알아보고자 한다. 대상 및 방법: 2001년 1월부터 2003년 6월까지 연세대학교 심장혈관병원에서 관상동맥우회출만을 시행받은 682명(off-pump CABG군: 424명, on-pump CABG: 258명)의 환자들 중 당뇨가 있는 환자 244명을 대상으로 하였다. 이 중 off-pump CABG는 154명, on-pump CABG는 90명의 환자들에서 시행하였다. 이 환자들을 대상으로 수술 전 위험요소들과 수술 후 결과를 비교하였다. 결과: 연령, 남녀 비 및 수술 전 고혈압 등의 위험요소와, 수술 전 뇌경색이나 심근경색의 기왕력 등 수술위험 요소도 두 군간의 통계적인 차이를 보이지 않았다. 이식편수는 on-pump CABG에서 유의하게 많았으나, 수술 시간은 off-pump CABG에서 통계적으로 유의하게 짧았고, 수술 후 강심제 사용빈도는 off-pump CABG에서 유의하게 낮았다. 수술 사망은 차이가 없었으며, 수술 후 측정한 CK-MB, 중환자실 인원기간 및 호흡기 사용시간은 off-pump CABG에서 통계적으로 유의하게 낮았다. 그러나 출혈로 인한 재수술, 수술 후 심근경색증, 감염, 신부전증, 신경학적 합병증 및 수술 후 입원 기간 등은 두 군간에 통제적 유의성이 없었다. 결론: 당뇨환자에서 시행한 off-pump CABG는 on-pump CABG에 비해 심근의 손상이 적으면서 수술 후 회복이 빨랐다. 따라서 두 방법 모두 좋은 결과를 보여 주었으나, off-pump CABG가 당뇨환자에서 좀 더 효과적인 수술 방법이라고 생각한다. 그러나 전향적인 연구 등 더 많은 연구가 필요하리라 생각한다.

Background: The type and regimen of anesthesia may affect perioperative hyperglycemia following major surgical stress. This study compared the effects of sevoflurane and propofol on the incidence of hyperglycemia and clinical outcomes in diabetic patients undergoing lung surgery. Methods: This retrospective study included 176 patients with type 2 diabetes mellitus who had undergone lung surgery. Blood glucose levels and clinical outcomes from the preoperative period to the first 2 postoperative days (PODs) were retrospectively examined in patients who received sevoflurane (group S, n= 87) and propofol (group P, n=89) for maintenance of general anesthesia. The primary endpoint was the incidence of persistent hyperglycemia (2 consecutive blood glucose levels >180 mg/dL [10.0 mmol/L]) during the perioperative period. The secondary composite endpoint was the incidence of major postoperative complications and 30-day mortality rate after surgery. Results: Blood glucose levels similarly increased from the preoperative period to the second POD in both groups (p=0.857). Although blood glucose levels at 2 hours after surgery were significantly lower in group P than in group S (p=0.022; 95% confidence interval for mean difference, -27.154 to -2.090), there was no difference in the incidence of persistent hyperglycemia during the perioperative period (group S, 70%; group P, 69%; p=0.816). The composite of major postoperative complications and all-cause in-hospital and 30-day mortality rates were also comparable between the two groups. Conclusion: Sevoflurane and propofol were associated with a comparable incidence of perioperative hyperglycemia and clinical outcomes in diabetic patients undergoing lung surgery.
