In recent years, wearable devices have seen a booming development, and the integration of wearable devices with clinical settings is an important direction in the development of wearable devices. The purpose of this study is to establish a prediction model for postoperative pulmonary complications (PPCs) by continuously monitoring respiratory physiological parameters of cardiac valve surgery patients during the preoperative 6-Minute Walk Test (6MWT) with a wearable device. By enrolling 53 patients with cardiac valve diseases in the Department of Cardiovascular Surgery, West China Hospital, Sichuan University, the grouping was based on the presence or absence of PPCs in the postoperative period. The 6MWT continuous respiratory physiological parameters collected by the SensEcho wearable device were analyzed, and the group differences in respiratory parameters and oxygen saturation parameters were calculated, and a prediction model was constructed. The results showed that continuous monitoring of respiratory physiological parameters in 6MWT using a wearable device had a better predictive trend for PPCs in cardiac valve surgery patients, providing a novel reference model for integrating wearable devices with the clinic.

OBJECTIVE: To investigate the effects of enhanced recovery after surgery (ERAS) on postoperative function and pain in total hip arthroplasty (THA) patients with high comorbidity. METHODS: Patients with THA who were admitted between January 2020 and January 2022 were selected as the study objects, and a total of 223 patients with high comorbidity met the selection criteria. Patients were randomly divided into two groups using the random envelope method. During perioperative period, 112 cases in the ERAS group were treated according to the ERAS protocol and 111 cases in the control group with the traditional protocol. There was no significant difference in gender, age, body mass index, Charlson comorbidity index, preoperative diagnosis, the type and number of the comorbidities, preoperative visual analogue scale (VAS) score between the two groups ( P>0.05). However, the Harris score of ERAS group was significantly lower than that of control group before operation ( P<0.05). Preoperative and postoperative hospital stays were recorded. The VAS score was used to evaluate the pain before operation, at 1 day after operation, at the leaving bed time, at the day after discharge, and at 2 weeks after operation. Harris score was used to evaluate hip function before operation and at 2 weeks, 1 month, 3 months, 6 months, and 12 months after operation. The incidence of complications, 30-day readmission rate, mortality rate, and patient's satisfaction were recorded. RESULTS: The length of preoperative hospital stay in ERAS group was significantly shorter than that in control group ( P<0.05). But there was no significant difference in the length of postoperative hospital stay between groups ( P>0.05). All patients in the two groups were followed up 12 months. The VAS score in the two groups after operation was lower than that before operation, and showed a gradually trend with the extension of time, with significant differences between different time points ( P<0.05). VAS scores of ERAS group were significantly lower than those of control group at different time points after operation ( P<0.05). The postoperative Harris scores in both groups were higher than those before operation, and showed a gradually increasing trend with the extension of time, with significant differences between different time points ( P<0.05). Harris scores of ERAS group at 2 weeks, 1 month, and 3 months after operation were significantly higher than those of control group ( P<0.05). Complications occurred in 2 cases (1.79%) of the ERAS group and 6 cases (5.41%) of the control group, with no significant difference in incidence ( P>0.05). In the control group, 1 case was readmitted within 30 days after operation, and 1 case died of severe pneumonia within 1 year of follow-up. There was no readmission or death in ERAS group, and there was no significant difference in the above indexes between the two groups ( P>0.05). At last follow-up, the satisfaction rate of patients in ERAS group was slightly higher than that in control group, but the difference was not significant ( P>0.05). CONCLUSION For THA patients with high comorbidity, ERAS protocol can shorten preoperative waiting time, better reduce pain, and improve hip function.

Objective:To compare the perioperative efficacy and safety of postoperative oral glucocorticoid and glucocorticoid stent implantation in patients with chronic rhinosinusitis with nasal polyps（CRSwNP） undergoing functional endoscopic sinus surgery（FESS）. Methods:Sixty patients with bilateral CRSwNP with similar degree of lesions were selected and divided into three groups: conventional surgical treatment group（20 cases）, glucocorticoid stent group（20 cases）, and oral glucocorticoid group（20 cases）. All three groups underwent routine FESS, patients in the sinus glucocorticoid stent group receiving sinus glucocorticoid stent placed in the ethmoid sinuses（one on each side） during surgery, and patients in the oral glucocorticoid group received postoperative oral methylprednisolone at a dose of 0.4 mg/kg per day for 7 days, followed by a tapering of 8 mg per week to 8 mg followed by maintenance therapy for 1 week, for a total of 3-4 weeks. Visual analog scale（VAS） scores were used to evaluate nasal congestion, rhinorrhea, olfaction, and facial pressure symptoms before surgery, as well as at 2, 4, 8, and 12 weeks after surgery. Nasal endoscopic Lund-Kennedy scores were recorded, and adverse reactions such as stent detachment, stent-related allergic reactions, sleep disorders, edema, gastrointestinal symptoms, rash/acne, behavioral/cognitive changes, weight gain, limb pain, and infection risk were documented. Results:The nasal congestion symptom scores at 2, 4, 8, and 12 weeks after surgery were significantly lower than those before operationin all three groups, and the differences were statistically significant（P<0.05）. The sinus glucocorticoid stent group exhibited significantly lower nasal congestion symptom scores at 4 and 8 weeks after surgery compared to the conventional surgical treatment group. The rhinorrhea symptom scores at 2, 8, and 12 weeks after surgery were significantly lower than preoperative scores in all three groups. Additionally, the sinus glucocorticoid stent group had significantly lower rhinorrhea scores than the conventional surgical treatment group at 2 weeks postoperatively. Concerning olfaction, the sinus glucocorticoid stent group showed a significant reduction in scores at 12 weeks postoperatively, while the oral glucocorticoid group exhibited significant improvement starting from 8 weeks after surgery. There were no statistically significant differences in nasal congestion, rhinorrhea, facial pressure, and olfaction scores between the sinus glucocorticoid stent and oral glucocorticoid groups at 2, 4, 8, and 12 weeks postoperatively. Nasal endoscopy scores revealed lower polyp scores and edema at 2, 4, 8, and 12 weeks postoperatively for all three groups compared to preoperative scores. The conventional surgical treatment group exhibited a significant reduction in nasal secretion scores starting from 8 weeks after surgery, while both the sinus glucocorticoid stent and oral glucocorticoid groups showed significant reductions starting from 2 weeks postoperatively, with scores significantly lower than those of the conventional surgical treatment group at 2 weeks. Scab/scar scores in the conventional surgical treatment group significantly decreased from 8 weeks after surgery, while both the sinus glucocorticoid stent and oral glucocorticoid groups exhibited significant reductions starting from 4 weeks. No statistically significant differences were observed in endoscopy scores（including polyps, edema, nasal secretion, scars, and scabs） between the sinus glucocorticoid stent and oral glucocorticoid groups at 2, 4, 8, and 12 weeks postoperatively. Regarding adverse reactions, no postoperative complications related to sinus glucocorticoid stent were observed in the sinus glucocorticoid stent group. In the oral glucocorticoid group,1 patient experienced irritability, and 1 patient experienced weight gain. Conclusion:The glucocorticoid stent implantation has comparable effects to oral glucocorticoid in improving postoperative nasal symptoms, reducing nasal mucosal edema, scar formation, and nasal secretion in patients with CRSwNP undergoing FESS, with a better safety profile.

Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

OBJECTIVES: The integrated model of prenatal diagnosis and postnatal treatment for congenital heart disease (CHD) leads to an increasing number of operation in infants. This study aims to reveal the risk factors for postoperative early mortality and delayed recovery in infants less than 3 months old, who underwent surgical treatment for CHD in the Department of Cardiovascular Surgery, Second Xiangya Hospital, Central South University during the past 5 years. METHODS: Clinical variables were collected via medical records. Delayed recovery was defined as the time of postoperative intubation, or cardiac intensive cure unit (CICU) stay, or hospital stay longer than its third quartile. Risk factors for early postoperative prognosis and the odds ratio (OR) were analyzed with logistic regression analysis. RESULTS: A total of 511 infants underwent surgical treatment for CHD from January 2016 to June 2020 were retrospectively reviewed, including 217 (42.5%) infants with complex CHD. The median age was 60 days (3 hours-90 days); and median weight was 4.5 (1.7- 8.4 kg). There were 26 postoperative mortalities, making the incidence at 5.1%, including 5 (5/294, 0.7%) mortalities in patients with uncomplicated CHD, and 21 (9.6%) mortalities in patients with complex CHD. Based on multivariable analysis, risk factors for postoperative mortality were diagnosis of complex CHD (OR=5.53, P<0.001), weight under 4.0 kg (OR=9.86, P<0.001), preoperative symptoms (OR=3.17, P=0.012), and emergency operation (OR=11.66, P<0.001). The median time for postoperative intubation, CICU stay, and hospital stay were 21.0 (0.3-979.0) hours, 3.0 (0.5-91.0) days, and 11.5 (3.0-105.0) days, respectively. A total of 177 (34.6%) infants delayed recover, with risk factors including diagnosis of complex CHD (OR=3.41, P=0.001), weight under 4.0 kg (OR=4.55, P<0.001), and preoperative symptoms (OR=3.91, P<0.001). CONCLUSIONS Surgical treatment for infants (<3 months) with CHD is still a challenge, particularly for infants with complex CHD and weight under 4.0 kg. We can improve the prognosis of CHD treatment in infants by establishing the integrated model of prenatal diagnosis and postnatal treatment to choose the most suitable time window, avoid symptoms before surgery, and reduce emergency operation.

OBJECTIVE: To observe the effect of electroacupuncture (EA) on laparoscope postoperative shivering in patients undergoing general anesthesia and explore its effect mechanism. METHODS: A total of 80 patients with elective laparoscopic resection of intestinal tumor under general anesthesia were randomly divided into an EA group and a tramadol group, 40 cases in each group. Thirty min prior to the end of the operation, in the EA group, EA was exerted at Neimadian and Zusanli (ST 36), with disperse-dense wave, 2 Hz/100 Hz in frequency, 1 mA in intensity, and lasting 30 min. In the tramadol group, tramadol hydrochloride injection was dropped intravenously, 1 mg/kg. The conditions of shivering, dizziness, nausea, vomiting and agitation were observed in the post-anesthesia care unit (PACU). Heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP) were observed before treatment (T₀), at the moment of extubation (T₁), in 3 min of extubation (T₂) and 1 h after operation (T₃). Using ELISA, at T₀ and T₃, the expression levels of interleukin 6 (IL-6) and 5-hydroxytryptamine (5-HT) in plasma were detected separately. Choking and agitation were recorded during extubation. RESULTS: ① In the EA group, the incidence of shivering, dizziness, nausea, vomiting and agitation in the PACU was lower than that in the tramadol group (P<0.05). ②Compared with T₀, HR, SBP and DBP were increased at T₁ and T₂ in the tramadol group (P<0.05). HR, SBP and DBP in the EA group were lower than the tramadol group at T₁ and T₂ (P<0.05). ③Compared with T₀, the expression levels of IL-6 and 5-HT in plasma were increased at T₃ in the tramadol group (P<0.05). The expression levels of IL-6 and 5-HT in the EA group were lower than the tramadol group at T₃ (P<0.05). ④The incidence of choking and agitation during exudation in the EA group was lower than that in the tramadol group (P<0.05). CONCLUSION Electroacupuncture can reduce the incidence of laparoscopic postoperative shivering under general anesthesia. The potential mechanism mays related to the modulation of the expression levels of IL-6 and 5-HT caused by surgical trauma.

INTRODUCTION: Post-anaesthesia care unit (PACU) delirium is a potentially preventable condition that results in a significant long-term effect. In a multicentre prospective cohort study, we investigate the incidence and risk factors of postoperative delirium in elderly patients undergoing major non-cardiac surgery. METHODS: Patients were consented and recruited from 4 major hospitals in Singapore. Research ethics approval was obtained. Patients older than 65 years undergoing non-cardiac surgery >2 hours were recruited. Baseline perioperative data were collected. Preoperative baseline cognition was obtained. Patients were assessed in the post-anaesthesia care unit for delirium 30-60 minutes after arrival using the Nursing Delirium Screening Scale (Nu-DESC). RESULTS Ninety-eight patients completed the study. Eleven patients (11.2%) had postoperative delirium. Patients who had PACU delirium were older (74.6±3.2 versus 70.6±4.4 years, P=0.005). Univariate analysis showed those who had PACU delirium are more likely to be ASA 3 (63.6% vs 31.0%, P=0.019), had estimated glomerular filtration rate (eGFR) of >60mL/min/1.73m2 (36.4% vs 10.6%, P=0.013), higher HbA1C value (7.8±1.2 vs 6.6±0.9, P=0.011), raised random blood glucose (10.0±5.0mmol/L vs 6.5±2.4mmol/L, P=0.0066), and moderate-severe depression (18.2% vs 1.1%, P=0.033). They are more likely to stay longer in hospital (median 8 days [range 4-18] vs 4 days [range 2-8], P=0.049). Raised random blood glucose is independently associated with increased PACU delirium on multivariate analysis.

With the breakthrough in surgical technology, pediatric liver transplantation (PLT) has achieved landmark development in China in recent years. In some high-volume centers, postoperative outcomes have even been comparable to the world-leading levels. However, postoperative infection remains a major factor affecting graft and recipient survivals. Thus, the Enhanced Recovery After Surgery Committee of the Chinese Research Hospital Association organized experts from multiple disciplines and formulated the consensus to improve the diagnosis, treatment and prevention of postoperative infections in PLT recipients. This consensus is based on the progress of domestic and international researches in this field and followed the principles of evidence-based medicine. It covers general and transplantation-specific infection, and is expected to provide reference for centers conducting or planning to conduct PLT.

Objective To develop a risk prediction model combining pre/intraoperative risk factors and intraoperative vital signs for postoperative healthcare-associated infection(HAI)based on deep learning. Methods We carried out a retrospective study based on two randomized controlled trials(NCT02715076,ChiCTR-IPR-17011099).The patients who underwent elective radical resection of advanced digestive system tumor were included in this study.The primary outcome was HAI within 30 days after surgery.Logistic regression analysis and long short-term memory(LSTM)model based on iteratively occluding sections of the input were used for feature selection.The risk prediction model for postoperative HAI was developed based on deep learning,combining the selected pre/intraoperative risk factors and intraoperative vital signs,and was evaluated by comparison with other models.Finally,we adopted the simulated annealing algorithm to simulatively adjust the vital signs during surgery,trying to explore the adjustment system that can reduce the risk of HAI. Results A total of 839 patients were included in this study,of which 112(13.3%)developed HAI within 30 days after surgery.The selected pre/intraoperative risk factors included neoadjuvant chemotherapy,parenteral nutrition,esophagectomy,gastrectomy,colorectal resection,pancreatoduodenectomy,hepatic resection,intraoperative blood loss>500 ml,and anesthesia time>4 h.The intraoperative vital signs significantly associated with HAI were in an order of heart rate>core body temperature>systolic blood pressure>diastolic blood pressure.Compared with multivariable Logistic regression model,random forest model,and LSTM model including vital signs only,this deep learning-based prediction model performed best(ACC=0.733,F1=0.237,AUC=0.728).The simulation via simulated annealing algorithm reduced the incidence of postoperative HAI.Moreover,the incidence decreased most in the case of reducing the initial annealing temperature and choosing the last 20% of surgery procedure. Conclusions This study developed a risk prediction model for postoperative HAI based on deep learning,which combined pre/intraoperative risk factors and intraoperative basic vital signs.Using simulated annealing algorithm to adjust intraoperative vital signs could reduce the incidence of postoperative HAI to some extent.
