Abstract
PURPOSE Preoperative cognitive impairment is a significant factor influencing post-operative delirium. We have been performing routine pre-operative comprehensive assessments, including evaluation of cognitive function, handgrip strength, oral hygiene, and nutritional status, in patients aged ≥ 65 years since April 2021. This study aimed to examine the completion rate of pre-operative comprehensive assessment and assess the prevalence of pre-operative undiagnosed cognitive impairment. METHODS In this prospective observational study including patients aged ≥ 65 years scheduled for elective surgery with general or regional anesthesia, cognitive impairment was defined as a Mini-Cog score ≤ 2, and its associations with handgrip strength, oral hygiene, and nutritional status were evaluated. Oral hygiene and nutritional status were assessed using an oral frailty self-checklist and the Mini Nutritional Assessment-Short Form, respectively. The incidence of pre-operative undiagnosed cognitive impairment was estimated, and its associated factors were explored with multiple logistic regression. RESULTS Among 331 eligible patients, the completion rate was 97.7% (305/312). The mean age was 74.8 years, and 13.1% (40/305) (95% confidence interval [CI], 9.7-17.3%) of the patients had pre-operative undiagnosed cognitive impairment. Multiple logistic regression revealed that handgrip strength (odds ratio [OR] = 0.94, 95%CI = 0.89-0.99) and oral frailty self-checklist score (OR = 1.19, 95%CI = 1.02-1.40) were associated with pre-operative undiagnosed cognitive impairment, while the Mini Nutritional Assessment-Short Form score was not significantly associated (OR = 0.97, 95%CI = 0.82-1.14). CONCLUSIONS Preoperative comprehensive assessment was feasible. The prevalence of pre-operative undiagnosed cognitive impairment was 13%, and poor handgrip strength and worse oral hygiene were significantly associated factors.

Abstract
PURPOSE Little evidence is available regarding bradypnea measured using continuous monitoring following cesarean section. We aimed to evaluate the rate of cumulative bradypnea time (total bradypnea time/total monitoring time) and its related factors in these parturients. METHODS This prospective observational study included women undergoing cesarean section under single-shot spinal anesthesia of 0.1 mg morphine. The Berlin Questionnaire was used to screen for sleep apnea syndrome preoperatively. Respiratory rate and oxygen saturation (SpO2) were monitored continuously using an adhesive acoustic respiration sensor and pulse oximeter, respectively, at least 6 h after cesarean section. Bradypnea was defined as a respiratory rate < 8 breaths/min lasting at least 25 s (sustained bradypnea) or at least 15 s (immediate bradypnea). Hypoxemia was defined as SpO2 < 92% lasting at least 25 s (sustained hypoxemia) or at least 15 s (immediate hypoxemia). Multiple regression analysis was applied to assess factors related to the rate of cumulative sustained bradypnea. RESULTS Of 159 patients, the Berlin Questionnaire was positive in 16.3%, and 77 (48.4%) experienced sustained bradypnea. The median rate of cumulative sustained bradypnea time was 0.70% (interquartile range 0.35-1.45%) without any related factors. The incidence of immediate bradypnea and sustained and immediate hypoxemia were 58.5%, 24.5%, and 37.7%, respectively. However, none of the factors were significant. CONCLUSION After cesarean section was performed with 0.1 mg intrathecal morphine, respiratory depression events were commonly observed. However, the rate of cumulative bradypnea time was very low and there were no related factors.

Abstract
Situs inversus totalis is a rare congenital anomaly. Most surgeons have seldom performed laparoscopy-assisted distal gastrectomy for situs inversus totalis. Inadequate knowledge regarding the anatomy of situs inversus totalis can result in increased intraoperative bleeding and prolonged operative time. A 74-year-old man was diagnosed with early gastric cancer with situs inversus totalis. We performed laparoscopy-assisted distal gastrectomy with D1+ lymphadenectomy and Billroth-I reconstruction by reversing the standard laparoscopy-assisted distal gastrectomy setup. Mirror images of the operative video of the standardized laparoscopy-assisted distal gastrectomy were created using video editing software. Lymphadenectomy was performed by indocyanine green fluorescence imaging of the lymphatic flow with operative time of 220 minutes and 100 mL intraoperative bleeding. The patient was discharged on postoperative day 10, without postoperative complications. Laparoscopy-assisted distal gastrectomy with indocyanine green navigation is safe and effective in patients with situs inversus totalis and is comparable with standard laparoscopy-assisted distal gastrectomy.

Abstract
This study investigated nurses' and patients' perceptions of hospital room environment and patient pajama design. Nurses working in a Japanese university hospital and patients aged 20 and older were surveyed. Over 75% of patients rated the hospital environment and hospital rooms as "very good" or "good," but less than one in three nurses rated them similarly. Patients were more likely than nurses to rate rental pajamas as "very good" or "good." Contrary to the nurses, only about one in four patients valued wearing well-designed pajamas. Nurses' and patients' perceptions differed regarding hospital pajamas, but not about improving hospital rooms.

Abstract
PURPOSE Orthopedic hip, knee, and spinal surgeries have a relatively high incidence of persistent postoperative pain, with the highest risk observed in Asian ethnicity. This study aimed to investigate the distribution of persistent pain at 1 year after surgery and its associated factors and effects on functional disability. METHODS This secondary analysis of a prospective observational study included 297 patients aged ≥ 55 years who underwent elective total hip arthroplasty, total knee arthroplasty, and spine and spinal cord surgeries under general anesthesia. Data were collected perioperatively and at 3 months and 1 year postoperatively to assess persistent postoperative pain on a numerical rating scale. RESULTS At 1 year postoperatively, 34.6% (103/297) of patients reported pain, with a score of ≥ 1 and a mean score of 1.2. Multivariable negative binomial regression analysis revealed that less preoperative bodily pain (risk ratio [RR], 0.97; 95% confidence interval [CI] 0.94-0.99), preoperative C-reactive protein (CRP) level (RR, 1.19; 95% CI 1.01-1.39), and spine and spinal cord surgeries (RR, 2.48; 95% CI 1.30-4.75) increased the risk of persistent pain at 1 year after surgery, which was a significant factor for predicting the 12-item World Health Organization Disability Assessment Schedule 2.0 score (p < 0.001). CONCLUSION The mean score for persistent pain at 1 year after surgery on the numerical rating scale was 1.2. Worse preoperative bodily pain, higher preoperative serum CRP level, and spine and spinal cord surgeries increased the persistent pain score at 1 year after surgery, which was associated with functional disability CLINICAL TRIAL REGISTRATION: This prospective observational study was registered on the University Hospital Medical Information Network (31 December 2015; UMIN000021671).

Abstract
Background Fever and associated shivering are frequent symptoms in patients with coronavirus disease 2019 (COVID-19). High body temperature activates the immune system, which might be beneficial. However, shivering leads to high oxygen demand. Case presentation A 38-year-old man diagnosed with COVID-19 was transferred to our intensive care unit (ICU). His oxygen saturation (SpO2) level was approximately 92–95% and was managed with a high flow nasal cannula. Six hours after admission to the ICU, he started shivering, and his systolic blood pressure rose above 200 mmHg. Concomitantly, his SpO2 levels decreased rapidly. Mechanical ventilation was started, but oxygenation could not be maintained, requiring the establishment of extracorporeal membrane oxygenation (ECMO). Conclusions COVID-19 is known to cause thrombosis in the pulmonary microvasculature at the early stage of the disease. Under these circumstances, caution should be paid since shivering may worsen the patient’s condition.

Abstract
Abstract
Background
Independent lung ventilation (ILV) allows separate positive end-expiratory pressures (PEEP) and inspiratory pressures for each lung. However, only a few articles have reported ILV management for lungs affected by different pathologies.
Case presentation
A 56-year-old man underwent video-assisted thoracic surgery for esophageal cancer. The right lung was injured during surgery, causing a bronchopleural fistula and necessitating chest drainage. On the third day in the intensive care unit, the patient’s oxygenation worsened during pressure support with continuous positive airway pressure ventilation. ILV was initiated for right-sided severe pneumothorax and left-sided atelectasis and pneumonia. ILV was continued for 2 days, and the patient’s trachea was successfully extubated the following day.
Conclusion
Applying high-level PEEP to the one lung and minimizing the airway pressure on the other lung could be achieved using ILV, which might contribute to successful tracheal extubation.

Abstract
The costoclavicular brachial plexus block (CBPB) has been receiving increasing attention as an effective technique for upper arm surgery conducted without phrenic paralysis. However, studies in children are lacking. CBPB was applied to a 10 year-old girl undergoing scheduled radial and ulnar osteotomy due to multiple cartilaginous exostoses and ulnar lengthening. CBPB was performed with a bolus administration of 10 mL of 0.25% levobupivacaine, and the catheter was sequentially replaced in the right costoclavicular space. After surgery, a continuous infusion of 0.17% levobupivacaine through a catheter was initiated at 2 mL/h, along with patient-controlled analgesia (PCA) of 3 mL 0.17% levobupivacaine with a 60-min lock out. The patient complained of 5/10 pain on the numerical rating scale (NRS) 2 h after surgery, which improved immediately after bolus administration. The analgesia induced by CBPB was otherwise effective (NRS ≤ 2). CBPB with PCA may provide adequate analgesia in paediatric cases.

Abstract
Background The nociception level (NOL) index discriminates noxious stimuli during surgery with high sensitivity and specificity. Although some studies have reported that a NOL-directed opioid protocol reduces intraoperative opioid consumption, one study implied that it might cause an unintended increase in the stress response. Therefore, we designed a study to investigate the effects of the NOL-directed opioid protocol and measure inflammatory biomarkers. Methods This single-centre RCT will enrol 54 patients undergoing robot-assisted laparoscopic radical prostatectomy. Eligible patients will be randomly allocated to receive (i) NOL-directed intraoperative opioid management (NOL group) or (ii) conventional intraoperative analgesic management (control group). The remifentanil infusion rate will be determined solely using the NOL index during surgery in the NOL group. The primary outcome will be the mean intraoperative remifentanil infusion rate. Secondary outcomes will include the plasma concentrations of three perioperative inflammatory biomarkers (interleukin-6, C-reactive protein, and cortisol) and the variation in the NOL index at the start of pneumoperitoneum and with postural changes. Conclusions This study is expected to accumulate evidence on the effects of NOL-directed analgesic opioid protocol and provide additional evidence regarding the variability of stress responses and the character of the NOL index.

Abstract
BACKGROUND The European Society for Clinical Nutrition and Metabolism recommends nutrition screening using the Mini Nutritional Assessment Short-Form (MNA-SF) in older adult patients preoperatively. However, the association of nutrition condition with postoperative complications is poorly documented. We aimed to identify preoperative nutrition status using the MNA-SF and to determine whether preoperative nutrition status affects postoperative outcomes. METHODS Inpatients aged ≥55 years who underwent elective abdominal surgery under general anesthesia between April 1, 2016, and December 28, 2018, were included. We assessed nutrition status using the MNA-SF before surgery. Multiple logistic regression including the MNA-SF score was applied to determine associated factors with our primary outcome, postoperative complications defined as Clavien-Dindo classification ≥3a. Secondary outcomes including length of hospital stay and unplanned readmission were compared between normal, at risk, and malnourished patients. RESULTS The data of 1248 patients with a mean age of 69 years were analyzed. The prevalence of at risk and malnutrition was 33.0% (412 of 1248) and 6.9% (87 of 1248), respectively. Overall, 12.4% (155 of 1248) had major postoperative complications, and the MNA-SF score was a significant predictor (odds ratio: 0.92, 95% CI: 0.86-0.99) after adjusting for confounders. Patients at risk of malnutrition and those with malnutrition had a longer hospital length of postoperative stay than normal patients (P = 0.001); however, there was no statistical significance in unplanned readmission rate between the three groups (P = 0.14). CONCLUSION Preoperative nutrition disorder was common, and it affected postoperative adverse outcomes. The MNA-SF score was associated with major postoperative complications.

Abstract
Thermus thermophilus has several minor lipid molecules with structures that have not been described yet. In this study, we identified a new lipid molecule in T. thermophilus HB8 with an amino group at the polar head, by detecting lipid spots with HPTLC and mass spectrometry. The structure of the lipid resembles an amino sugar phospholipid, except for the glucosamine that lacks an acetyl group. We named this amino phosphoglycolipid PGLN, and proposed its synthetic pathway from a precursor, phosphatidyl-glyceric alkylamine. The primary amine structure of PGLN may contribute to high temperature adaptation through electrostatic interactions between the head groups. No amino phospholipid has been identified in T. thermophilus HB8 so far. PGLN is discovered by detecting lipid spots with HPTLC and mass spectrometry. PGLN is a newly identified amino phosphoglycolipid without an acetyl group. PGLN may play an important role in high temperature adaptation.

Abstract
An 80-year-old woman presented to our emergency department with vomiting which had begun half a day prior to presentation. She had undergone open mesh plug repair for a right obturator hernia 1 year prior to presentation. Computed tomography detected recurrence of the right obturator hernia. Since intestinal viability was maintained, manual reduction of the incarcerated intestine was performed. The patient was admitted to our department to monitor delayed intestinal perforation. Laparoscopic transabdominal preperitoneal repair for obturator hernia was performed 5 days after admission. A self-fixating mesh was placed over the obturator hernia defect and femoral ring without tacking. The patient was discharged on postoperative day 6 without postoperative complications. At the 4-month follow-up, no signs of hernia recurrence or neuropathy were observed. Laparoscopic transabdominal preperitoneal repair for recurrent obturator hernia status post-open mesh plug repair by using self-fixating mesh is a safe and suitable procedure.

Abstract
Given neuromuscular blockade (NMB) can affect the amplitude and detection success rate of motor-evoked potentials (MEP), sugammadex may be administered intraoperatively. We evaluated the factors affecting the degree of residual NMB (i.e., the train-of-four [TOF] ratio) and the relationship between TOF ratio and MEP detection success rate in Japanese patients undergoing spine surgery. This single-center retrospective observational study included adults who underwent spine surgery under propofol/remifentanil anesthesia, received rocuronium for intubation, and underwent myogenic MEP monitoring after transcranial stimulation. TOF ratios were assessed using electromyography. Sugammadex was administered after finishing the MEP setting and the TOF ratio was ≤0.7. To identify factors affecting the TOF ratio, TOF ratio and MEP detection success rate were simultaneously measured after finishing the MEP setting; to compare the time from intubation to the start of MEP monitoring after NMB recovery between sugammadex and spontaneous recovery groups, multivariable analyses were performed. Of 373 cases analyzed, sugammadex was administered to 221 (59.2%) cases. Age, blood pressure, hepatic impairment, and rocuronium dose were the main factors affecting the TOF ratio. Patients with higher TOF ratios (≥0.75) had higher MEP detection success rates. The time from intubation to the start of MEP monitoring after NMB recovery was significantly shorter in patients administered sugammadex versus patients without sugammadex (P < .0001). The MEP detection success rate was higher in patients with a TOF ratio of ≥0.75. Sugammadex shortened the time from intubation to the start of MEP monitoring after NMB recovery.

Abstract
BACKGROUND Patients with alcohol drinking habits have less nausea and vomiting during chemotherapy because of cytochrome P450 enzyme induction. However, few studies have examined the effect of alcohol consumption on postoperative nausea and vomiting (PONV). We conducted a study to clarify the relationship between alcohol drinking habits and PONV. METHODS Data of patients undergoing hepatectomy under general anesthesia between 2016 and 2020 were retrospectively collected. Since alcohol drinking habits vary by gender, age, and comorbidities, propensity score matching was performed to adjust patient background before multivariate logistic regression analysis. RESULTS Seventy-eight patients in the alcohol consumption and non-consumption groups were matched by propensity matching. Univariate analysis showed that alcohol consumption (P = 0.04) and male (P < 0.001) were the factors that significantly reduced PONV. Multiple logistic regression analysis including intraoperative factors showed that alcohol consumption (odds ratio, 0.36; 95% confidence interval [CI], 0.15-0.90) and female (odds ratio, 5.34; 95% CI, 2.0-14.2) were associated with PONV as factors affecting PONV. CONCLUSION Patients with no alcohol drinking habits may be at higher risk of PONV.

Abstract
PURPOSE Preoperative prediction of functional status after surgery is essential when practicing patient-centered medicine. We aimed to evaluate the incidence and factors associated with postoperative functional disability or all-cause mortality. Secondarily, we sought to describe the trajectory of disability in this population. METHODS Adults aged ≥ 55 yr who underwent elective noncardiac surgery under general anesthesia in a tertiary care hospital were followed up one year after surgery. Pre- and intraoperative factors associated with a composite outcome of postoperative functional disability or all-cause mortality were assessed using a multiple logistic regression. The sequential changes in the 12-item World Health Organization Disability Assessment Schedule (WHODAS) 2.0 score were described and stratified by surgical invasiveness. RESULTS Of the 2,921 patients included, 293 experienced postoperative functional disability (10.0%; 95% confidence interval [CI], 8.9 to 11.1) and 124 died (4.2%; 95% CI, 3.5 to 5.0). In a multiple regression model, the potentially modifiable risk factors, body mass index ≥ 30 kg·m-2 and poor preoperative nutritional status, were significantly associated with the primary composite outcome, as well as nonmodifiable factors such as age, preoperative comorbidities, and blood loss volume. Changes in the 12-item WHODAS 2.0 disability score varied between different levels of surgical invasiveness and types of surgery. CONCLUSION Within one year after surgery, one in ten patients experienced postoperative functional disability and one in 20 died. We identified potentially modifiable factors (obesity, poor nutritional status) associated with these adverse outcomes.

[PMID: 35461251 PMCID: PMC9034527 DOI: 10.1186/s13019-022-01829-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 04/10/2022] [Indexed: 11/23/2022] Open
Abstract
Background Aberrant right subclavian artery (ARSA) accompanied by non-recurrent inferior laryngeal nerve (NRILN) is a rare anomaly. In cases of thoracic esophageal carcinoma associated with ARSA and NRILN, surgeons must take extra care not to injury these vessels and nerves. We believe semi-prone thoracoscopic esophagectomy to be a surgical approach that can safely deal with such an anomaly.
Case presentation A 70-year-old man complained of feelings of chest constriction. Endoscopic examination revealed an esophageal tumor and computed tomography showed an ARSA. We performed semi-prone thoracoscopic esophagectomy for case with ARSA and NRILN. We identified these anomalies during esophagectomy, and we could complete surgery without injury these vessels and nerves. The patient had an uneventful recovery and discharged 22 days after surgery. Conclusions Semi-prone thoracoscopic esophagectomy for esophageal carcinoma can be performed safely with a wide operative field, and is an excellent procedure for dissecting esophageal carcinoma in patients with ARSA and NRILN.

Efficacy of modified thoracoabdominal nerves block through perichondrial approach in open gynecological surgery: a prospective observational pilot study and a cadaveric evaluation. BMC Anesthesiol 2022; 22:107. [PMID: 35428204 PMCID: PMC9010447 DOI: 10.1186/s12871-022-01652-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2021] [Accepted: 04/11/2022] [Indexed: 11/10/2022] Open
Abstract
Background Modified thoracoabdominal nerves block through perichondrial approach (M-TAPA) was first described as a peripheral nerve block by Tulgar in 2019. This technique provides an analgesic effective range from Th7–11 with a single puncture per side. Although the efficacy and effective duration of M-TAPA have been reported, further examination is required. Therefore, this study aimed to evaluate the analgesic range and effective duration of M-TAPA in open gynecologic surgery. Methods Following approval, 10 adult female patients scheduled for open radical hysterectomy via a vertical incision or laparotomy using a midline incision from under the xiphoid process to the symphysis pubis were enrolled. The primary outcome was the number of anesthetized dermatomes at 2 and 24 h postoperatively. Secondary outcomes included numerical rating scale scores and the total amount of fentanyl used. Cadaveric evaluation was performed to assess the spread of the dye. Results The median numbers (interquartile range) of anesthetized dermatomes at 2 and 24 h postoperatively were 6 (5–7) and 6.5 (5–7) in the anterior cutaneous branch area and 5 (4–7) and 7 (5–7) in the lateral cutaneous branch area, respectively. There was an 85% chance of simultaneously acquiring analgesia in areas innervated by Th8–11, including complete block in areas innervated by the anterior cutaneous branches of Th9–10. Cadaveric evaluation showed the spread of the dye in Th8–11. Conclusions M-TAPA may have analgesic effects in the areas supplied by the anterior cutaneous branches of Th8–11.

Abstract
OBJECTIVE Factors related to perioperative dental injury have likely changed as a variety of airway devices and preventive measures have been introduced. This retrospective chart review used data from an institutional registry to evaluate the incidence, timing, and contributing factors of patient self-reported dental injury and to assess the impact of dental injury on patient satisfaction. METHODS Multivariate logistic analysis was performed on the records of 14,820 patients using the incidence of dental injury as the dependent variable and covariates in the anesthesia registry and a postoperative questionnaire as independent variables to investigate factors significantly associated perioperative dental injury. In addition, satisfaction with the anesthesia service was compared between patients with and without injury using a matched-pair population. RESULTS A total of 101 dental injuries were identified. Of those, 25% were associated with intubation and extubation in the operating room, while most other injuries occurred postoperatively. Duration of anesthesia (odds ratio [OR], 1.02; 95% confidence interval [CI], 1.00-1.03) and emergency surgery (OR, 1.92; 95% CI, 1.11-3.30) were independently associated with perioperative dental injury. Dental injury did not significantly decrease a patient's satisfaction with the anesthesia service (P = .441). CONCLUSION Most perioperative dental injuries are unrelated to anesthesia procedures. However, the duration of anesthesia and emergency surgery were significantly associated with perioperative dental injury, while decreased patient satisfaction was not.

Abstract
Coagulation and fibrinolytic mechanisms are enhanced in patients with coronavirus (COVID-19), but disturbances in the balance of both functions in COVID-19 patients remain unclear. We assessed global coagulation and fibrinolysis in plasma from 167 COVID-19 patients (mild/moderate/severe: 62/88/17, respectively) on admission using clot-fibrinolysis waveform analysis (CFWA). Maximum coagulation velocity (|min1|) and maximum fibrinolysis velocity (|FL-min1|) were expressed as ratios relative to normal plasma. Ten patients (6.0%) developed thrombosis, 5 (3.0%) had bleeding tendency, and 13 (7.8%) died during admission. FDP levels increased with severity of COVID-19 symptoms (mild/moderate/severe; median 2.7/4.9/9.9 μg/mL, respectively). The |min1| ratios were elevated in all categories (1.27/1.61/1.58) in keeping with enhanced coagulation potential, with significant differences between mild cases and moderate to severe cases. The |FL-min1| ratios were also elevated in all groups (1.19/1.39/1.40), reflecting enhanced fibrinolytic potential. These data identified coagulation dominance in moderate to severe cases, but balanced coagulation and fibrinolysis in mild cases. There were significant differences in FDP and TAT, but no significant differences in |min1| or |FL-min1| ratios, between patients with and without thrombosis. CFWA monitoring of coagulation and fibrinolysis dynamics could provide valuable data for understanding hemostatic changes and disease status in COVID-19 patients.

Abstract
BACKGROUND Chronic postsurgical pain negatively affects postoperative recovery. We aimed to assess the association between pre-operative functional disability and chronic postsurgical pain. METHODS This secondary analysis of a prospective observational study included 920 inpatients aged≥55 years undergoing elective abdominal surgery. We assessed functional disability using the 12-item World Health Organization Disability Assessment Schedule 2.0 before surgery and measured postoperative pain using a numerical rating scale at a postanaesthetic clinic 3 months and 1 year after surgery. We performed multiple logistic regression analysis to determine associations with chronic postsurgical pain 1 year after surgery. We analysed the sequential pain score using a mixed-effects model in patients with and without pre-operative functional disability. The primary outcome in this study was chronic postsurgical pain and its associated factors with a focus on preoperative functional disability. The secondary outcome was pain trajectories in patients with and without preoperative functional disability. RESULTS Of the 899 patients included in the analysis, 11.9% had chronic postsurgical pain 1 year later. The multiple logistic regression analysis revealed that pre-operative functional disability was associated with this outcome (OR 2.80, 95% CI, 1.70 to 4.59) as well as use of pre-operative pain medication (OR 2.74, 95% CI, 1.24 to 6.03) and pain numerical rating scale at the postanaesthetic clinic (OR 1.19, 95% CI 1.10 to 1.29). The pain trajectories were different in the presence or absence of functional disability (P<0.001) and the time of measurement (P<0.001). CONCLUSIONS Pre-operative functional disability was associated with chronic postsurgical pain and pain trajectories.

Abstract
Abstract
Background
Postoperative delirium is an important complication after surgery, including urological surgery. This study evaluated the incidence of postoperative delirium and its associated factors after transurethral resection of bladder tumor in adult patients.
Methods
Patients aged ≥20 years who underwent elective transurethral resection of bladder tumor under general anesthesia from April 2016 to November 2020 were included. Patient demographic and intraoperative data, including the administration of 5-aminolevulinic acid and hypotension, defined as a mean arterial pressure value < 60 mmHg, were evaluated. The primary outcome was the incidence of postoperative delirium assessed using a chart-based method. The factors associated with postoperative delirium were explored using multiple logistic regression analysis. Postoperative lengths of stay between patients with and without postoperative delirium were compared using the Mann–Whitney U-test.
Results
Of 324 eligible patients with a median age of 76, 26 patients experienced postoperative delirium, with an incidence rate of 8.0% (95% confidence interval, 5.06–10.9). Age (odds ratio 1.13, 95% confidence interval 1.05–1.22, p = 0.001) and body mass index (odds ratio 0.83, 95% confidence interval 0.71–0.97, p = 0.02) were associated with postoperative delirium. Postoperative length of stay between patients with or without postoperative delirium was not significantly different (6 vs 6 days, p = 0.18).
Conclusions
The incidence of postoperative delirium after transurethral resection of bladder tumor under general anesthesia in this study was 8.0%. Older age and low body mass index were associated with development of postoperative delirium.
