ABSTRACT
Objective:To investigate the effects of different levels of ophthalmic surgical stimulation on blood glucose in patients with type 2 diabetes mellitus(T2DM).Methods:From Mar to Oct 2021,236 patients with T2DM who underwent ophthalmic surgery in our hospital were enrolled,including 71 cases of secondary surgery,89 cases of tertiary surgery,and 76 cases of quaternary surgery.According to the operation time,the 236 patients were divided into groups A(＜60 min),B(60-120 min)and C(＞120 min).The preoperative and postoperative blood glucose levels were compared in patients with different levels of surgery,and in groups A,B and C.Results:The postoperative blood glucose level was lower than that before surgery in secondary and tertiary surgery,and it was higher than that before surgery in quaternary surgery(P＜0.05).The fluctuation value of blood glucose in secondary and tertiary surgery was higher than that in quaternary surgery(P＜0.05).In groups A,B and C,the postoperative blood glucose level was lower than that before surgery in secondary and tertiary surgery(P＜0.05).In group A,there was no significant difference in the blood glucose before and after surgery in quaternary surgery(P＞0.05),and in groups B and C,the postoperative blood glucose was higher than that before surgery in quaternary surgery(P＜0.05).In group A,there was no difference in the fluctuation value of blood glucose at different levels of surgery(P＞0.05).In group B,the fluctuation value of blood glucose in patients with secondary and tertiary surgery was higher than that in quaternary surgery(P＜0.05).In group C,the fluctuation value of blood glucose in patients with tertiary and quaternary surgery was higher than that in patients with secondary surgery(P＜0.05).Conclusions:For ophthalmic surgery patients with T2DM,the postoperative blood glucose values of patients undergoing secondary and tertiary surgery generally show a downward trend,while the postoperative blood glucose value of patients undergoing quaternary surgery generally shows an upward trend.It is suggested that clinical workers should actively manage the perioperative blood glucose of patients with high-level surgery.
ABSTRACT
Objective:To explore the prognostic effect and safety of neurally adjusted ventilatory assist (NAVA) mode on the patients with severe neurological cerebrovascular disease undergoing mechanical ventilation.Methods:A prospective study was conducted. Fifty-four patients with cerebrovascular disease undergoing mechanical ventilation admitted to the neurosurgery intensive care unit (NSICU) of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from December 2020 to May 2022 were enrolled. They were divided into NAVA group and pressure support ventilation (PSV) group by computer random number generator with 27 patients in each group. The ventilation time of the two groups was ≥72 hours. The general basic data of the two groups were recorded. The time without mechanical ventilation 28 days after enrollment, total length of mechanical ventilation, survival rate of 90 days after enrollment, length of NSICU stay, total length of hospital stay, NSICU mortality, in-hospital mortality, Glasgow outcome score (GOS), complications related to mechanical ventilation, and changes of respiratory mechanics indexes, arterial blood gases, vital signs, and diaphragm function indexes were observed.Results:The time without mechanical ventilation 28 days after enrollment in the NAVA group was significantly longer than that in the PSV group [days: 22 (15, 26) vs. 6 (0, 23), P < 0.05]. However, there were no significant differences in the total length of mechanical ventilation, 90-day survival rate, length of NSICU stay, total length of hospital stay, NSICU mortality, in-hospital mortality, GOS score, and incidence of mechanical ventilator-related complications between the two groups. In terms of respiratory mechanics parameters, the expiratory tidal volume (VTe) on 3 days after mechanical ventilation of patients in the NAVA group was significantly lower than that on 1 day and 2 days, and significantly lower than that in the PSV group [mL: 411.0 (385.2, 492.6) vs. 489.0 (451.8, 529.4), P < 0.01]. Minute ventilation (MV) at 2 days and 3 days in the NAVA group was significantly higher than that at 1 day, and significantly higher than that in the PSV group at 2 days [L/min: 9.8 (8.4, 10.9) vs. 7.8 (6.5, 9.8), P < 0.01], while there was no significant change of MV in the PSV group. At 1 day, peak airway pressure (Ppeak) and mean airway pressure (Pmean) in the NAVA group were significantly lower than those in the PSV group [Ppeak (cmH 2O, 1 cmH 2O≈0.098 kPa): 14.0 (12.2, 17.0) vs. 16.6 (15.0, 17.4), Pmean (cmH 2O): 7.0 (6.2, 7.9) vs. 8.0 (7.0, 8.2), both P < 0.05]. However, there was no significant difference in the Ppeak or Pmean at 2 days and 3 days between the two groups. In terms of arterial blood gas, there was no significant difference in pH value between the two groups, but with the extension of mechanical ventilation time, the pH value at 3 days of the two groups was significantly higher than that at 1 day. Arterial partial pressure of oxygen (PaO 2) at 1 day in the NAVA group was significantly lower than that in the PSV group [mmHg (1 mmHg≈0.133 kPa): 122.01±37.77 vs. 144.10±40.39, P < 0.05], but there was no significant difference in PaO 2 at 2 days and 3 days between the two groups. There was no significant difference in arterial partial pressure of carbon dioxide (PaCO 2) or oxygenation index (PaO 2/FiO 2) between the two groups. In terms of vital signs, the respiratory rate (RR) at 1, 2, and 3 days of the NAVA group was significantly higher than that of the PSV group [times/min: 19.2 (16.0, 25.2) vs. 15.0 (14.4, 17.0) at 1 day, 21.4 (16.4, 26.0) vs. 15.8 (14.0, 18.6) at 2 days, 20.6 (17.0, 23.0) vs. 16.7 (15.0, 19.0) at 3 days, all P < 0.01]. In terms of diaphragm function, end-inspiratory diaphragm thickness (DTei) at 3 days in the NAVA group was significantly higher than that in the PSV group [cm: 0.26 (0.22, 0.29) vs. 0.22 (0.19, 0.26), P < 0.05]. There was no significant difference in end-expiratory diaphragm thickness (DTee) between the two groups. The diaphragm thickening fraction (DTF) at 2 days and 3 days in the NAVA group was significantly higher than that in the PSV group [(35.18±12.09)% vs. (26.88±8.33)% at 2 days, (35.54±13.40)% vs. (24.39±9.16)% at 3 days, both P < 0.05]. Conclusions:NAVA mode can be applied in patients with neuro-severe cerebrovascular disease, which can prolong the time without mechanical ventilation support and make patients obtain better lung protective ventilation. At the same time, it has certain advantages in avoiding ventilator-associated diaphragm dysfunction and improving diaphragm function.
ABSTRACT
OBJECTIVE@#To investigate the incidence and risk factors of hypothermia in patients with acute renal injury (AKI) receiving continuous renal replacement therapy (CRRT), and to compare the effects of different heating methods on the incidence of hypothermia in patients with CRRT.@*METHODS@#A prospective study was conducted. AKI patients with CRRT who were admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to December 2022 were enrolled as the study subjects. Patients were divided into dialysate heating group and reverse-piped heating group according to randomized numerical table method. Both groups were provided with reasonable treatment mode and parameter setting by the bedside physician according to the patient's specific condition. The dialysis heating group used the AsahiKASEI dialysis machine heating panel to heat the dialysis solution at 37 centigrade. The reverse-piped heating group used the Barkey blood heater from the Prismaflex CRRT system to heat the dialysis solution, and the heating line temperature was set at 41 centigrade. The patient's temperature was then continuously monitored. Hypothermia was defined as a temperature lower than 36 centigrade or a drop of more than 1 centigrade from the basal body temperature. The incidence and duration of hypothermia were compared between the two groups. Binary multivariate Logistic regression analysis was used to explore the influencing factors of hypothermia during CRRT in AKI patients.@*RESULTS@#A total of 73 patients with AKI treated with CRRT were eventually enrolled, including 37 in the dialysate heating group and 36 in the reverse-piped heating group. The incidence of hypothermia in the dialysis heating group was significantly lower than that in the reverse-piped heating group [40.5% (15/37) vs. 69.4% (25/36), P < 0.05], and the hypothermia occurred later than that in the reverse-piped heating group (hours: 5.40±0.92 vs. 3.35±0.92, P < 0.01). Patients were divided into hypothermic and non-hypothermic groups based on the presence or absence of hypothermia, and a univariate analysis of all indicators showed a significant decrease in mean arterial pressure (MAP) in hypothermic patients (n = 40) compared with the non-hypothermic patients [n = 33; mmHg (1 mmHg ≈ 0.133 kPa): 77.45±12.47 vs. 94.42±14.51, P < 0.01], shock, administration of medium and high doses of vasoactive drug (medium dose: 0.2-0.5 μg×kg-1×min-1, high dose: > 0.5 μg×kg-1×min-1) and CRRT treatment were significantly increased [shock: 45.0% (18/40) vs. 6.1% (2/33), administration of medium and high doses of vasoactive drugs: 82.5% (33/40) vs. 18.2% (6/33), administration of CRRT (mL×kg-1×h-1): 51.50±9.38 vs. 38.42±10.97, all P < 0.05], there were also significant differences in CRRT heating types between the two groups [in the hypothermia group, the main heating method was the infusion line heating, which was 62.5% (25/40), while in the non-hypothermia group, the main heating method was the dialysate heating, which was 66.7% (22/33), P < 0.05]. Including the above indicators in a binary multivariate Logistic regression analysis, it was found that shock [odds ratio (OR) = 17.633, 95% confidence interval (95%CI) was 1.487-209.064], mid-to-high-dose vasoactive drug (OR = 24.320, 95%CI was 3.076-192.294), CRRT heating type (reverse-piped heating; OR = 13.316, 95%CI was 1.485-119.377), and CRRT treatment dose (OR = 1.130, 95%CI was 1.020-1.251) were risk factors for hypothermia during CRRT in AKI patients (all P < 0.05), while MAP was protective factor (OR = 0.922, 95%CI was 0.861-0.987, P < 0.05).@*CONCLUSIONS@#AKI patients have a high incidence of hypothermia during CRRT treatment, and the incidence of hypothermia can be effectively reduced by heating CRRT treatment fluids. Shock, use of medium and high doses of vasoactive drug, CRRT heating type, and CRRT treatment dose are risk factors for hypothermia during CRRT in AKI patients, with MAP is a protective factor.

OBJECTIVE@#To explore the predictive value of diaphragmatic thickening fraction (DTF) combined with Medical Research Council-score (MRC score) on the outcome of weaning from mechanical ventilation in ICU-acquired weakness (ICU-AW) patients.@*METHODS@#A retrospective case-control study was conducted. The clinical data of mechanically ventilated patients with an MRC score of less than 48 admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College from January 2022 to March 2023 were collected, including general information, ultrasound indicators, MRC scores, main clinical outcomes, and weaning outcomes. Patients were divided into successful weaning group and failed weaning group according to whether the patient could maintain effective autonomous breathing for at least 48 hours without using an invasive or non-invasive ventilator. The clinical data of the two groups were compared. Receiver operator characteristic curve (ROC curve) was plotted to analyze the predictive value of DTF and MRC score alone or in combination for successful weaning of patients.@*RESULTS@#A total of 87 patients were enrolled, of which 58 were successful weaning and 29 were failed weaning. There were no statistically significant differences in general data such as gender, age, underlying disease, heart rate (HR), mean arterial pressure (MAP), pH value, blood lactic acid (Lac), oxygenation index (PaO2/FiO2), and severity scores between the two groups. Compared with the failed weaning group, the DTF and MRC scores of patients in the successful weaning group were significantly increased [DTF: (26.02±2.68)% vs. (22.79±5.40)%, MRC score: 38.90±2.78 vs. 33.24±3.78, both P < 0.05]. The duration of mechanical ventilation and the length of ICU stay of patients in the successful weaning group were significantly shorter than those in the failed weaning group [duration of mechanical ventilation (hours): 102.21±32.60 vs. 113.14±41.34, length of ICU stay (days): 6.48±2.18 vs. 10.11±4.01, both P < 0.05], and the re-intubation rate and ICU hospitalization cost were significantly lowered [re-intubation rate: 6.90% (4/58) vs. 27.59% (8/29), ICU hospitalization cost (10 000 RMB): 4.99±0.87 vs. 7.85±2.45, both P < 0.05]. ROC curve analysis showed that the area under the ROC curve (AUC) of DTF and MRC score for predicting successful weaning in ICU-AW mechanical ventilation patients was 0.839 [95% confidence interval (95%CI) was 0.746-0.931] and 0.799 (95%CI was 0.701-0.899), respectively. Using DTF ≥ 25.01% as the optimal cut-off value to predict successful weaning, the sensitivity was 82.76%, and the specificity was 72.41%. Predicting successful weaning based on an optimal cut-off value of MRC score of ≥ 35.50 had a sensitivity of 79.31% and a specificity of 70.69%. Based on the DTF ≥ 25.01% combined with MRC score ≥ 35.50, it was predicted that the weaning would be successful, with an AUC of 0.887 (95%CI was 0.812-0.962), sensitivity increased to 89.70%, and specificity increased to 79.30%.@*CONCLUSIONS@#The DTF and MRC score have good guiding value for the selection of weaning timing and predicting the weaning outcomes in ICU-AW patients. Compared with independent DTF and MRC score, the combination of DTF and MRC score improves the predictive value of successful weaning in ICU-AW patients.

Objective:To observe the application effect of high-flow nasal canula oxygen therapy (HFNC) after extubation in patients with mechanical ventilation (MV) in the intensive care unit (ICU).Methods:A prospective study was conducted. From January 2018 to June 2020, 163 MV patients admitted to Yijishan Hospital of Wannan Medical College were enrolled, and they were divided into HFNC group (82 cases) and traditional oxygen therapy group (81 cases) according to the oxygen therapy model. The patients included in the study were given conventional treatment according to their condition. In the HFNC group, oxygen was inhaled by a nasal high-flow humidification therapy instrument. The gas flow was gradually increased from 35 L/min to 60 L/min according to the patient's tolerance, and the temperature was set at 34-37 ℃. The fraction of inspiration oxygen (FiO 2) was set according to the patient's pulse oxygen saturation (SpO 2) and SpO 2 was maintained at 0.95-0.98. A disposable oxygen mask or nasal cannula was used to inhale oxygen in the traditional oxygen therapy group, and the oxygen flow was 5-8 L/min, maintaining the patient's SpO 2 at 0.95-0.98. The differences in MV duration before extubation, total MV duration, intubation time, reintubation time, extubation failure rate, ICU mortality, ICU stay, and in-hospital stay were compared between the two groups, and weaning failure were analyzed. Results:There was no significant differences in MV duration before extubation (days: 4.33±3.83 vs. 4.15±3.03), tracheal intubation duration (days: 4.34±1.87 vs. 4.20±3.35), ICU mortality [4.9% (4/82) vs. 3.7% (3/81)] and in-hospital stay [days: 28.93 (15.00, 32.00) vs. 27.69 (15.00, 38.00)] between HFNC group and traditional oxygen therapy group (all P > 0.05). The total MV duration in the HFNC group (days: 4.48±2.43 vs. 5.67±3.84) and ICU stay [days: 6.57 (4.00, 7.00) vs. 7.74 (5.00, 9.00)] were significantly shorter than those in the traditional oxygen therapy group, the reintubation duration of the HFNC group was significantly longer than that of the traditional oxygen therapy group (hours: 35.75±10.15 vs. 19.92±13.12), and the weaning failure rate was significantly lower than that of the traditional oxygen therapy group [4.9% (4/82) vs. 16.0% (13/81), all P < 0.05]. Among the reasons for weaning failure traditional oxygen therapy group had lower ability of airway secretion clearance than that of the HFNC group [8.64% (7/81) vs. 0% (0/82), P < 0.05], there was no statistically differences in the morbidity of heart failure, respiratory muscle weakness, hypoxemia, and change of consciousness between the two groups. Conclusion:For MV patients in the ICU, the sequential application of HFNC after extubation can reduce the rate of weaning failure and the incidence of adverse events, shorten the length of ICU stay.

ABSTRACT
Objective:To investigate the role and mechanism of splenic myeloid-derived suppressor cells (MDSCs) in sepsis-induced adrenal injury (SAI).Methods:Thirty male C57 mice aged 6-8 weeks were randomly divided into normal control group ( n = 5), sham operation group (Sham group, n = 5), sepsis model group [cecal ligation and perforation (CLP) group, n = 10] and sepsis+splenectomy group (CLPS group, n = 10). The sepsis model of mice was reproduced by CLP method. In Sham group, only the cecum was opened and separated, then closed, without CLP. In CLPS group, the spleen was removed before CLP. In normal control group, no challenge was given. After 24 hours, the rats were sacrificed by anesthesia, and peripheral blood, spleen, bone marrow, and bilateral adrenal glands were harvested. The pathological of adrenal gland was assessed by hematoxylin-eosin (HE) staining under optical microscope. The ratio of MDSCs in peripheral blood, spleen and bone marrow was determined by flow cytometry. The expressions of MDSCs surface antigen CD11b, Gr-1 and interleukins (IL-6, IL-1β) mRNA in adrenal tissue were measured by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). Western Blot was used to detect the expressions of mammalian rapamycin target protein (mTOR) pathway related proteins including total mTOR (T-mTOR), phosphorylation of mTOR (p-mTOR) and caspase-3. Results:The adrenal cortex and medulla of the normal control group and Sham group were intact and the structure was clear under optical microscope, while in the CLP group, the adrenal gland showed edema, cortical hemorrhage and cell edema. Compared with the CLP group, the adrenal tissue injury was significantly reduced in the CLPS group. Compared with the normal control group and Sham group, MDSCs ratio in the peripheral blood was significantly increased and significantly reduced in the spleen in the CLP group, but there was no significant difference in bone marrow, the expression levels of CD11b, Gr-1, IL-6, IL-1β mRNA and caspase-3 protein were increased significantly and p-mTOR protein expression was significantly decreased in adrenal tissue, there was no significant difference in the expression of T-mTOR protein. Compared with the CLP group, in the CLPS group, the MDSCs ratio in the peripheral blood was significantly decreased (0.143±0.011 vs. 0.324±0.023, P < 0.01), the expression levels of CD11b, Gr-1, IL-6 , IL-1β mRNA and caspase-3 protein in adrenal gland were significantly decreased [CD11b mRNA (2 -ΔΔCt): 2.90±0.56 vs. 5.74±0.13, Gr-1 mRNA (2 -ΔΔCt): 2.71±0.14 vs. 4.59±0.46, IL-6 mRNA (2 -ΔΔCt): 2.44±0.64 vs. 5.17±1.04, IL-1β mRNA (2 -ΔΔCt): 3.58±0.52 vs. 4.44±0.26, caspase-3 protein (caspase-3/GAPDH): 0.05±0.01 vs. 0.13±0.02, all P < 0.01], the p-mTOR protein expression was significantly increased (p-mTOR/GAPDH: 0.61±0.11 vs. 0.27±0.04, P < 0.01). Conclusions:The spleen is the major source of MDSCs in SAI. Splenectomy can attenuate SAI by reducing mobilization of MDSCs and activating the mTOR signaling pathway.
ABSTRACT
Objective:To provide a reference for extracorporeal membrane oxygenation (ECMO) inter-hospital transport during coronavirus disease 2019 (COVID-19), based on the transport experience of 6 patients with severe H1N1 influenza virus pneumonia using ECMO.Methods:Clinical data of patients with severe H1N1 influenza virus pneumonia implemented by ECMO in the First Affiliated Hospital of Wannan Medical College from October 2018 to December 2019 were retrospective analyzed, including general information, ECMO transport distance, time, clinical parameters before and after ECMO, including the patients' oxygenation index (PaO 2/FiO 2), respiratory rate (RR), pulse blood oxygen saturation (SpO 2), arterial blood carbon dioxide partial pressure (PaCO 2), and pH value, various complications during transport, mechanical ventilation time, patients' prognosis and other indicators. Experience from the aspects of personal protection, transport process and equipment, team cooperation, mid-transit monitoring, quality control, etc., was summarized to provide suggestions for patients with severe COVID-19 using ECMO during inter-hospital transport and protection. Results:A total of 6 patients with severe H1N1 influenza virus pneumonia were transported on ECMO. All patients were transported to the intensive care unit (ICU) of the First Affiliated Hospital of Wannan Medical College by the ECMO transport team after the establishment of ECMO in the local hospital. The transfer distance was 11 to 197 km, with an average of (93.8±58.6) km; the transfer time was 30 to 150 minutes, with an average of (79.2±40.6) minutes. Two patients experienced a drop in ECMO flow and SpO 2 during the process, and the main reason was insufficient volume, which was improved after fluid resuscitation and posture adjustment. All patients maintained SpO 2 above 0.93. Six patients survived and were discharged. ECMO assisted time was 4-9 days, with an average of (6.5±1.5) days; mechanical ventilation time was 7-24 days, and median time was 10.0 (8.0, 14.5) days. No H1N1 transmission occurred in medical personnel. To achieve good therapeutic effect, the main experience was to choose the proper timing and mode of ECMO; intact transportation vehicles and equipment to reduce or avoid mechanical complications; the effective management of respiration and circulation during the transportation to avoid ventilation-associated lung injury (VALI) and serious hypoxemia; the appropriate space for the transfer team to quickly handle various critical situations; and personal protection to avoid infection. Conclusion:With an experienced ECMO transport team, good transport equipment, comprehensive protection measures, reasonable transport procedures, and a perfect emergency plan, it is safe to use ECMO transport for COVID-19 patients.
