OBJECTIVE: To explore the effect of light music therapy on delirium in intensive care unit (ICU) patients undergoing invasive mechanical ventilation, and provide evidence-based support for clinical prevention of delirium. METHODS: A prospective randomized controlled trial was conducted. 140 patients with invasive mechanical ventilation admitted to the department of respiratory and critical care medicine of First Affiliated Hospital of Guangxi Medical University from January 2024 to January 2025 were enrolled. The patients were divided into intervention group and control group using a random number table method. The control group received routine treatment and nursing care, while the intervention group received light music therapy three times a day for 30 minutes each time for 7 consecutive days. The confusion assessment method-ICU (CAM-ICU) was used to evaluate delirium, and the incidence of delirium within 7 days was statistically analyzed. Richmond agitation-sedation score (RASS), critical care pain observation tool (CPOT) score, mechanical ventilation duration, the length of ICU stay, and ICU stay expenses were record. RESULTS: 129 cases were ultimately included, including 64 cases in the control group and 65 cases in the intervention group. There was no statistically significant difference in baseline data between the two groups, indicating comparability. The incidence of delirium in the intervention group was significantly lower than that in the control group (27.7% vs. 51.6%, χ ² = 7.687, P = 0.006). There was no significantly difference in RASS score between the two groups before enrollment (P = 0.840). After intervention, the RASS score in the intervention group significantly decreased, from 2.00 points on the 1st day of enrollment to 0.00 points on the 7th day, while the control group only decreased from 2.00 points to 1.50 points. The decreasing trend of the intervention group was more pronounced, especially on the 3rd day (P = 0.047) and the 7th day (P =0.005), with significant differences between the groups. The time effect (F = 18.929, P < 0.001), group effect (F = 6.655, P = 0.011), and time group interaction effect (F = 7.372, P < 0.001) of the two groups of RASS score were significant, suggesting that light music therapy has better timeliness and sustainability in improving patients' sedation status. There was no significantly difference in CPOT score between the two groups before enrollment (P = 0.902). After intervention, the CPOT score in the intervention group rapidly decreased from 3.00 points before enrollment to 1.00 points on the 1st day, and continued until the 7th day, while the control group showed a slower decrease from 2.50 points to 2.00 points and only dropped to 1.00 points on the 7th day. There were significant differences on 1st day and 3rd day between two groups (both P < 0.05). The time effect (F = 28.125, P < 0.001), group effect (F = 11.580, P = 0.001), and time group interaction effect (F = 4.048, P = 0.020) of the two groups of CPOT score were significant, indicating that light music therapy has better pain control, but the interaction effect is low, indicating that the impact of the intervention on the CPOT score was mainly concentrated in the early stage (1-3 days), and the long-term effect may be influenced by other factors. Compared with the control group, the intervention group showed a significant reduction in mechanical ventilation time (days: 10.57±2.94 vs. 11.95±3.74, P = 0.021) and the length of ICU stay (days: 14.91±4.37 vs. 17.53±4.83, P = 0.002). The ICU hospitalization expenses of the intervention group was slightly lower than that of the control group [ten thousand yuan: 22.431 (12.473, 28.489) vs. 29.362 (11.996, 41.389)], but the difference was not statistically significant (P = 0.086). CONCLUSIONS Light music therapy can effectively reduce the incidence of delirium in patients undergoing invasive mechanical ventilation, improve consciousness and pain perception, shorten mechanical ventilation time and hospital stay, and has significant clinical promotion value high-quality studies.

OBJECTIVES: To investigate the effect of sequential sedative and analgesic drugs in preventing delirium and withdrawal symptoms in children after ventilator weaning. METHODS: A retrospective analysis was performed on 61 children who were admitted and received mechanical ventilation support for ≥5 days in the Pediatric Intensive Care Unit of Dongguan Children's Hospital Affiliated to Guangdong Medical University from December 2019 to September 2021. The children were divided into a control group (30 children with no maintenance of analgesic and sedative drugs after ventilator weaning) and an observation group (31 children with sequential sedative and analgesic drugs maintained for 48 hours after ventilator weaning). The two groups were compared in terms of the Sophia Observation Withdrawal Symptoms Scale (SOS) score, the Pediatric Delirium Scale (PD) score, the Richmond Agitation-Sedation Scale (RASS) score, and the incidence rates of delirium or withdrawal symptoms at 24 and 72 hours after ventilator weaning. RESULTS: There was no significant difference in the incidence rate of delirium at 24 hours and 72 hours after ventilator weaning between the two groups (P>0.05). Compared with the control group, the observation group had significantly lower incidence rate of withdrawal symptoms and scores of SOS, PD, and RASS scales at 24 hours and 72 hours after ventilator weaning (P<0.01). CONCLUSIONS Sequential sedation and analgesia after ventilator weaning can reduce the incidence of withdrawal symptoms within 72 hours after ventilator weaning, but it cannot reduce the incidence rate of delirium.

OBJECTIVES: Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) are common operative neurocognitive disorders, which places a heavy burden on patients, families and society. Therefore, it is very important to search for preventive drugs. Previous studies have demonstrated that perioperative use of dexmedetomidine resulted in a decrease the incidence of POD and POCD. But the specific effect of dexmedetomidine on elderly patients undergoing hepatic lobectomy and its potential mechanism are not clear. This study aims to evaluate the efficacy of intraoperative use of dexmedetomidine on preventing POD and POCD in elderly patients undergoing hepatic lobectomy and the influence on the balance between proinflammation and anti-inflammation. METHODS: This trial was designed as a single-center, prospective, randomized, controlled study. One hundred and twenty hospitalized patients from January 2019 to December 2020, aged 60-80 years old with American Society of Anesthesiologists (ASA) II-III and scheduled for hepatic lobectomy, were randomly allocated into 3 groups (n=40) using a random number table: A C group, a Dex1 group, and a Dex2 group. After anesthesia induction, saline in the C group, dexmedetomidine [0.3 μg/(kg·h)] in the Dex1 group, and dexmedetomidine [0.6 μg/(kg·h)] in the Dex2 group were infused until the end of operation. The incidences of hypotension and bradycardia were compared among the 3 groups. Confusion Assessment Method (CAM) for assessing POD and Mini Mental State Examination (MMSE) for evaluating POCD were recorded and venous blood samples were obtained for the determination of neuron specific enolase (NSE), TNF-α, IL-1β, and IL-10 at the different time below: the time before anesthesia (T0), and the first day (T1), the third day (T2), the fifth day (T3), and the seventh day (T4) after operation. RESULTS: Compared with the C group, the incidences of bradycardia in the Dex1 group or the Dex2 group increased (both P<0.05) and there was no difference in hypotension in the Dex1 group or the Dex2 group (both P>0.05). The incidences of POD in the C group, the Dex1 group, and the Dex2 group were 22.5%, 5.0%, and 7.5%, respectively. The incidences of POD in the Dex1 group or the Dex2 group declined significantly as compared to the C group (both P<0.05). However, there is no difference in the incidence of POD between the Dex1 group and the Dex2 group (P>0.05). The incidences of POCD in the C group, the Dex1 group, and the Dex2 group were 30.0%, 12.5%, and 10.0%, respectively. The incidences of POCD in the Dex1 group and the Dex2 group declined significantly as compared to the C group (both P<0.05). And no obvious difference was seen in the incidence of POCD in the Dex1 group and the Dex2 group (P>0.05). Compared with the C group, the level of TNF-α and IL-1β decreased and the level of IL-10 increased at each time points (from T1 to T4) in the Dex1 group and the Dex2 group (all P<0.05). Compared with the Dex1 group, the level of IL-1β at T2 and IL-10 from T1 to T3 elevated in the Dex2 group (all P<0.05). Compared with the T0, the concentrations of NSE in C group at each time points (from T1 to T4) and in the Dex1 group and the Dex2 group from T1 to T3 increased (all P<0.05). Compared with the C group, the level of NSE decreased from T1 to T4 in the Dex1 group and the Dex2 group (all P<0.05). CONCLUSIONS Intraoperative dexmedetomidine infusion can reduce the incidence of POCD and POD in elderly patients undergoing hepatic lobectomy, and the protective mechanism appears to involve the down-regulation of TNF-α and IL-1β and upregulation of IL-10 expression, which lead to rebalance between proinflammation and anti-inflammation.

OBJECTIVE: To study the effect of soothing liver, relieving depression, invigorating spleen and reinforcing blood on reducing delirium in elderly patients with hip fracture. METHODS: From December 2014 to June 2018, 180 elderly patients with hip fracture admitted were divided into treatment group and placebo group according to the order of admission:90 patients in treatment group were treated with Jiawei Xiaoyao Powder(JWXYP), including 32 males and 58 females, with an average age of(72.12±4.92), involving 67 cases of femoral trochanter fractures and 23 cases of femoral neck fractures; 35 cases underwent dynamic hip screw fixation, 31 cases underwent intramedullary fixation and 24 cases underwent artificial hip replacement. In the placebo group, 90 patients were treated with placebo, including 37 males and 53 females, with an average age of(72.91±5.43) years old, involving 69 cases of femoral trochanteric fractures and 21 cases of femoral neck fractures, including 37 cases underwent dynamic hip screw fixation, 30 cases underwent intramedullary fixation and 23 cases underwent artificial hip replacement. The age, sex, injury site, intraoperative bleeding volume, postoperative drainage, operation time, anesthesia time, post-operative pain score, post-operative hemoglobin, post-operative CRP, delirium severity(DRS) score and delirium occurrence were observed and compared between the two groups. RESULTS: All patients were followed up until delirium returned to normal, postoperative delirium was found in 12 cases (13.33%) in the treatment group and in 39 cases(43.33%) in the placebo group, the treatment group was significantly better than the placebo group. The monitoring indexes of the two groups were compared:post-operative pain score(=0.002), post-operative hemoglobin(=0.012), post-operative CRP(=0.042). CONCLUSIONS JWXYP can relieve liver depression, invigorate spleen and invigorate blood circulation, reduce pain, inflammatory stimulation and supplement blood volume after operation, and significantly reduce the incidence of delirium after operation.

BACKGROUND: Postinfarction ventricular septal rupture is associated with mortality as high as 85~90%, if it is treated medically. This report documents our experience with postinfarction ventricular septal rupture that was treated surgically. MATERIAL AND METHOD: We retrospectively reviewed the medical records of 11 patients who were operated on due to postinfarction ventricular septal rupture between August 1996 and August 2006. There were 4 men and 7 women, with a mean age of 70+/-11 years (age range: 50~84 years). The location of the rupture was anterior in 7 cases and posterior in 4 cases. The interval between the onset of acute myocardial infarction and the occurrence of the ventricular septal rupture was 2.0+/-1.3 days (range: 1~5 days). Operation was performed at an average of 2.4+/-2.7 days (range: 0~8 days) after the diagnosis of septal rupture. Preoperative intraaortic balloon pump therapy was performed in 10 patients. RESULT: The infarct exclusion technique was used in all cases. Coronary artery bypass grafting was done in 8 cases, with the mean number of distal anastomosis being 1.0+/-0.8. There was one operative death. In 2 patients, reoperation was performed due to a residual septal defect. The postoperative morbidities were transient atrial fibrillation (n=7), paroxysmal supraventricular tachycardia (n=1), low cardiac output syndrome (n=3), bleeding reoperation (n=2), delayed sternal closure (n=2), acute renal failure (n=2), pneumonia (n=1), intraaortic balloon pump-related thromboembolism (n=1), and transient delirium (n=2). Nine patients have been followed up for a mean of 38+/-40 months except for one follow-up loss. There have been 3 late deaths. At the latest follow-up, all 6 survivors were in a good functional class. CONCLUSION: We demonstrated satisfactory operative and midterm results with our strategy of preoperative intraaortic balloon pump therapy, early repair of septal rupture by infarct exclusion and combined coronary revascularization.
