ABSTRACT
Objective:To design a tracheotomy cannula cuff filling device for hyperbaric oxygen therapy, which is convenient for clinical operation, improves work efficiency and reduces the incidence of aspiration pneumonia.Methods:This study was a randomized controlled trial. From July 2020 to June 2022, 90 patients with tracheotomy who were treated with hyperbaric oxygen in the First Hospital of Jiaxing were selected as the research objects. According to the random number table method, the patients were divided into the experimental group and the control group, with 45 cases in each group. In the experimental group, the cuff pressure was maintained by the tracheotomy cannula cuff filling device, and in the control group, the traditional water injection method was used to maintain the cuff pressure. The operation time, infection index and incidence of aspiration pneumonia were compared between the two groups.Results:The operation time in the experimental group was (6.33 ± 1.31) s lower than that in the control group (40.96 ± 3.70) s, and the difference was statistically significant ( t=-59.11, P<0.05). Body temperature, C-reactive protein and procalcitonin after treatment in the experimental group were (36.91 ± 0.83) ℃, (34.59 ± 16.25) mg/L, (1.57 ± 0.82) μg/L, respectively, lower than those in the control group (37.42 ± 0.72) ℃, (44.18 ± 18.10) mg/L, (2.45 ± 0.92) μg/L, the differences were statistically significant ( t=-3.09, -2.64, -4.73, all P<0.05). The difference of white blood cell count post-treatment between the two groups was not statistically significant ( P>0.05). The incidence of aspiration pneumonia in the experimental group was 11.11%(5/45) lower than 31.11%(14/45) in the control group, and the difference was statistically significant ( χ2=5.17, P<0.05). Conclusions:The application of tracheotomy cannula cuff filling device can simplify the operation process, reduce the incidence of infection and aspiration pneumonia, and optimize the clinical work.
ABSTRACT
In the emergency department, open endotracheal suctioning for mechanically ventilated patients with endotracheal intubation will lead to the spread of respiratory droplets and aerosols, polluting the surrounding environment and medical staff. The traditional heat-and-moisture exchanger has the effect of warming and humidifying, and can block pathogenic microorganisms, but it does not have the function of inserting a sputum suction tube. When the heat-and-moisture exchanger is pulled out for sputum suction, it is easy to cause sputum splash, which pollutes the surrounding environment and medical personnel. The addition of closed sputum suction devices will increase the economic burden on patients. Thus, the medical staff of emergency department of the First People's Hospital of Tongxiang City of Zhejiang Province designed a new type of heat-and-moisture exchanger with anti-splash sputum suctioning function and obtained the National Utility Model Patent of China (ZL 2021 2 0017615.0). The new heat-and-moisture exchanger is mainly composed of a receiving cavity, a connecting tube, a sputum suction tube intubation tube, a sealing valve, etc. The disposable sputum suction tube can be used to insert sputum suction, and at the same time, it can prevent the secretion from splashing to ensure sealing. The patent combines the humidification and pathogen blocking functions of the heat-and-moisture exchanger with the anti-splash sputum suctioning function, which is suitable for use in the emergency and critical care medicine departments and has clinically practical value.
ABSTRACT
Dysglycemia is independently associated with the mortality of critically ill patients. Therefore, the management of blood glucose plays an important role in comprehensive therapy. It is suggested that the same target value of blood glucose (7.8-10.0 mmol/L) should not be set for all critically ill patients. Instead, it should be individually set based on the causes of the patient's admission and the status of blood glucose before admission. For this reason, there is an urgent need for a convenient protocol and method to regulate the dosage of insulin. The first hospital of Jiaxing, collaborating with information engineers, developed a modified eProtocol-insulin for domestic population with mathematical modeling and developed an Application Software (APP), which is convenient for clinical use. This is the first eProtocol-insulin and smart device APP for critically ill patients in China.
ABSTRACT
Objective:To explore the application of folding transfer shelf in the transportation of critically ill patients.Methods:Patients transferred from the emergency department to the intensive care unit (ICU) admitted to the First Hospital of Jiaxing from January 1st to December 31st in 2019 were enrolled. The patients were divided into study group and control group by whether or not using the self-developed folding transfer shelf. The incidence of adverse events, the stability rate of vital signs and the transport time were compared between the two group.Results:A total of 437 patients were enrolled in the study, with 222 in the study group (which used the self-developed folding transfer shelf) and 215 in the control group (which used the conventional stretcher). The baseline data such as gender, age, disease status and disease severity were balanced between the two groups. The stability rate of vital signs in the study group was higher than that in the control group (89.19% vs. 82.33%, P < 0.05). The transfer time in the study group was shorter than that in the control group (minutes: 6.39±1.35 vs. 7.61±1.34, P < 0.01). The total incidence of adverse transport events in the study group was lower than that in the control group (2.25% vs. 10.23%, P < 0.01). The incidence of miscarriage of emergent materials and instrument falling in the study group were lower than those in the control group (0% vs. 2.79%, 0% vs. 2.33%, both P < 0.05). Conclusions:The folding transfer shelf could reduce the transport risk of critical ill patients, especially the risk of miscarriage and falling of rescue instrument. The application of folding transfer shelf could regulate the management of transport, keep the vital signs of patients stable during transport, shorten the transport time, and facilitate an efficient and high-quality transport.
ABSTRACT
Multifunctional monitors including electrocardiograph monitor, oxygen saturation monitor, blood pressure monitor, temperature monitor, arterial pressure monitor are often used for critically ill patients in hospitals. Each function monitoring part is equipped with multiple data monitoring wires. Due to the disorderly distribution, monitoring wires are often intertwined with each other. The medical staff will spend much time for careful identification and energy in emergency use and the improper operation of the equipment leads to its damage, which could affect data monitoring result, delay the diagnosis and treatment, and cause certain medical risks. In addition, the data line is often exposed to the external environment, which has a certain impact on its service life. Moreover, the distribution of the data line is disorderly, affecting the hospital environment and appearance. Thus, a kind of medical wire storage box was designed, which could realize the monitoring data cables in proper storage and neat distribution, reducing the workload of medical staff. The wire storage box has won the National Utility Model Patent of China (ZL 2017 2 1826195.0). The introduction goes as following. The storage box includes upper box body, lower box body and winding roller. The receptacle on the upper box body and the lower box body cooperate to form a cylindrical receptacle chamber for the winding roller. The side wall of the winding roller is designed with spiral winding groove which could help wrap the excessively long wires in the winding groove for storage. When multiple boxes need to be used simultaneously, the strip and slot on both sides of the lower box are used to splice the cable boxes together which improves the uniformity with less space use. The medical storage box is easy to make and can effectively avoid line friction and damage, prolong the line service life, and save department cost. In addition, it avoids the involvement between the lines, and improves the work efficiency. It also helps to keep the department environment tidy, which complies with "6S" management requirements, with good clinical application value.
ABSTRACT
In daily medical work, most of the critically ill patients who cannot move by themselves are pulled and lifted by manpower, often relying on the cooperation of many doctors and nurses, which not only increases the risk of transfer and patients' discomfort, but also causes certain skeletal and muscle damage to the porters. The emergency department of the First Hospital of Jiaxing City, Zhejiang Province designed a kind of patient transfer device, and obtained the National Utility Model Patent (ZL 2018 2 0579844.X). The transfer device is composed of upper frame, lower frame and base. The upper frame and the lower frame are rectangular and in a horizontal position. The upper frame can slide laterally through the circular tubes which are fixed on the lower frame. The lower part of the base is provided with four universal foot brake wheels. During the usage, the booster frame facilitates the transfer of patients by the rolling and two sliding tracks of the circular tube, which can make patients move smoothly and comfortably, and reduce the working intensity of the transporter. This device has good practical value.

Objective To observe the effects of insulin caliper for blood glucose control on glycemic central tendency, fluctuation and incidence of hypoglycemia, etc., in emergent and critical patients to evaluate its application value.Methods A prospective single-blinded randomized parallel controlled intervention study was conducted. One hundred patients with severe hyperglycemia requiring treatment with insulin infusion admitted to emergency department and intensive care unit (ICU) of the First Hospital of Jiaxing from November 2015 to November 2017 were enrolled, and they were divided into the caliper group (used patented product insulin calipers for blood glucose control to adjust insulin dose for blood glucose control) and the conventional group (used paper-based insulin dose modification scheme to adjust insulin dose for blood glucose control) on average by random number table, 50 in each group. The gender, age, acute physiology and chronic health evaluation Ⅱ(APACHEⅡ), sequential organ failure assessment (SOFA), the principal diseases, main factors affecting blood glucose (hepatic and renal insufficiency, hypoglycemic drugs, glucocorticoids, mechanical ventilation, enteral nutrition, parenteral nutrition, intravenous glucose use, etc.), blood glucose levels at each time node (once every 2 hours after insulin use and once every 4 hours after 16-72 hours), glycemic coefficient of variance (CV), glycemic lability index (GLUGLI) and mean amplitude of glycemic excursion (GLUMAGE), insulin dose, incidence of hypoglycemia, proportion of achieving the glucose control target at each time point, the length of ICU stay and hospitalization cost per patient were recorded and compared between the two groups.Results After excluding those with incomplete data and withdraw in the midway, 92 patients were enrolled in the analysis finally,47 in caliper group and 45 in conventional group. There were no significant differences in the incidence of the gender, age, APACHEⅡ, SOFA, presence of infection at admission, previous diabetes history, glycosylated hemoglobin level, blood glucose at admission, proportion of patients after surgery, major diseases at admission and major factors affecting blood glucose between the two groups. A total of 1379 blood glucose measurements were obtained in the caliper group and 1332 blood glucose measurements were obtained in the conventional group. The glycemic measurements in caliper group were significantly lower than that in conventional group at each time point from 6-72 hours. Compared with conventional group, GLUGLI and GLUMAGE were significantly decreased in the caliper group [GLUGLI: 12.96 (8.73, 19.58) vs. 23.27 (13.07, 44.61), GLUMAGE (mmol/L): 0.66±0.22 vs. 0.87±0.28, bothP< 0.01]; there was a tendency towards decreasing incidence of hypoglycemia in the caliper group [8.51％ (4/47) vs. 15.56％ (7/45)], but no statistical difference was found (P > 0.05); the proportion of achieving the glucose control target was significantly increased in the caliper group [41.99％ (579/1379) vs. 27.18％ (362/1332),P < 0.01]. There were no significant differences in glycemic CV, insulin dose, proportion of hypoglycemic measurements in total measurements, and the length of ICU stay, the length of hospital stay, incidence of nosocomial infection, patient prognosis and cost between the two groups.Conclusion For emergent and critical patients, insulin caliper for blood glucose control presents favorable application value for achieving glucose control target, reducing glycemic fluctuation, and lowering the incidence of hypoglycemia.Clinical trial registration China clinical trial registration center, ChiCTR1800015024

ABSTRACT
Objective To investigate the expression of miR-520d-3p in 2 and 4 Gy X-ray irradiated A549 cells, serum samples of non-small cell lung cancer (NSCLC) patients and its significance. Methods Real time quantitative PCR (RT-qPCR) was employed to detect the expression miR-520d-3p in 2 and 4 Gy X-ray irradiated A549 cells in vitro. Besides, 0, 2 and 4 Gy X-ray irradiated A549 cells were used to prepare animal model of nude mice lung metastasis through mainline. The expressions of miR-520d-3p and lung tissue of nude mice were detected, and the serum samples of NSCLC patients were collected to test the expression of miR-520d-3p . Results Compared with the control group ( 0 Gy ) , the expression of miR-520d-3p was up-regulated significantly in 2 and 4 Gy X-ray irradiated A549 cells after 48 hours (1.00±0.03, 1.47±0.10, 1.84 ±0.09 respectively), and there was a significant difference (F= 94.350, P= 0.000). Furthermore, compared the control group with injection after 10 weeks, the expressions of miR-520d-3p in nude mice lung tissue in 0, 2 and 4 Gy X-ray irradiated groups were increased (2.33 ±0.13, 8.24 ±0.25, 3.46 ±0.14, respectively) (F=1.787, P= 0.227), and the expressions in serum were increased (11.43±2.30, 10.22±4.62, 8.99 ±3.67, respectively) (F= 1.547, P= 0.246). Out of 20 serum samples of NSCLC patients (including 10 cases of adenocarcinoma, 10 cases of squamous carcinoma ), 11 cases (55%) were detected with up-regulated miR-520d-3p expression. Conclusions 2 and 4 Gy X-ray could increase the expression of miR-520d-3p of A549 cells in vitro and in vivo, which might be correlated with the enhanced invasion and metastasis of A549 cells induced by X-ray in vitro and in vivo. Furthermore, the expressions of miR-520d-3p were increased significantly in over 50%serum samples of NSCLC patients, which might be a new marker for the diagnosis of NSCLC.

ABSTRACT
Objective To investigate the efficiency of closed tracheal suction system (CTSS) using novel splash-proof ventilator circuit component on ventilator-associated pneumonia (VAP) and the colonization of multiple-drug resistant bacteria (MDR) in patients undergoing mechanical ventilation (MV) prevention.Methods A prospective single-blinded randomized parallel controlled intervention study was conducted. 330 severe patients admitted to the intensive care unit (ICU) of the First Hospital of Jiaxing from January 2014 to May 2016 were enrolled, and they were divided into open tracheal suction group, closed tracheal suction group, and splash-proof suction group on average by random number table. The patients in the three groups used conventional ventilator circuit component, conventional CTSS, and CTSS with a novel splash-proof ventilatorcircuit component for MV and sputum suction, respectively. The incidence of VAP, airway bacterial colonization rate, MDR and fungi colonization rate, duration of MV, length of ICU and hospitalization stay, and financial expenditure during hospitalization, as well as the in-hospital prognosis were recorded.Results After excluding patients who did not meet the inclusion criteria, incomplete data, backed out and so on, 318 patients were enrolled in the analysis finally. Compared with the open tracheal suction group, the total incidence of VAP was decreased in the closed tracheal suction group and splash-proof suction group [20.95% (22/105),21.90% (23/105) vs. 29.63% (32/108)], but no statistical difference was found (both P > 0.05), and the incidence of VAP infections/1000 MV days showed the same change tendency (cases: 14.56, 17.35 vs. 23.07). The rate of airway bacterial colonization and the rate of MDR colonization in the open tracheal suction group and splash-proof suction group were remarkably lower than those of closed tracheal suction group [32.41% (35/108), 28.57% (30/105) vs. 46.67% (49/105), 20.37% (22/108), 15.24% (16/105) vs. 39.05% (41/105)] with significantly statistical differences (allP 0.05). Compared with theclosed tracheal suction group, the duration of MV, the length of ICU and hospitalization stay were shortened in the open tracheal suction group and splash-proof suction group [duration of MV (days): 8.00 (4.00, 13.75), 8.00 (5.00, 13.00) vs. 9.00 (5.00, 16.00); the length of ICU stay (days): 10.00 (6.00, 16.00), 11.00 (7.00, 19.00) vs. 13.00 (7.50, 22.00); the length of hospitalization stay (days): 16.50 (9.25, 32.00), 19.00 (10.50, 32.50) vs. 21.00 (10.00, 36.00)], and financial expenditure during hospitalization was lowered [10 thousand Yuan: 4.95 (3.13, 8.62), 5.47 (3.84, 9.41) vs. 6.52 (3.99, 11.02)] without significantly statistical differences (allP > 0.05). Moreover, no significantly statistical difference was found in the in-hospital prognosis among the three groups.ConclusionsCTSS performed using novel splash-proof ventilator circuit component shared similar advantages in preventing VAP with the conventional CTSS. Meanwhile, it is superior because it prevented the colonization of MDR and high price in the conventional CTSS.Clinical Trail Registration Chinese Clinical Trial Registry, ChiCTR-IOR-16009694.

The critical patients admitted from January 2011 to December 2013 in ICU of the First Hospital of Jiaxing in Zhejiang Province were enrolled,and their clinical data with positive Candida culture and drug susceptibility results in specimens of sputum,urine,blood,ascites,bile, etc were collected. In the study of these 3 years in ICU,the situation of Candida infection,the distribution of positive specimen,the condition of distribution of different strains of Candida,and the Candida tolerance to antifungal drugs were analyzed. Results From 2011 to 2013,2 412 times of patients(including one patient had admitted into ICU for more than one time)were admitted into ICU in which 407 cases were of Candida infection(16.9%),and the rate of Candida infection was rising gradually in the 3 years〔2011 to 2013 Candida positive rates were 13.4%(77/573), 16.1%(146/907),19.7%(184/932)〕,the difference being statistically significant(P<0.01). In the 407 strains of Candida,166 strains(40.8%)were isolated from sputum,157(38.6%)from urine,53 strains(13.0%)ascites, 13 strains(3.1%)blood,11 strains(2.7%)bile,7 strains(1.7%)from other specimens. The strain distribution of Candida was mainly as follows:Candida albicans(174 strains),Candida glabrata(131 strains),Candida tropicalis (83 strains),Candida parapailosis(5 strains),Candida krusei(12 strains),and 2 strains of rare Candida portugal and Lipolztica. From 2011 to 2013,the highest tolerance of Candida albicans,Candida glabrata,Candida tropicalis to fluconazole,itraconazole,Fushita Yasu and other antifungal drugs was in 2013,and the lowest was in 2012,the rates of tolerance of the above 3 strains of Candida to amphotericin B being 0,to itraconazole being the highest(10.9%, 27.8%,9.6%,respectively),to Fushita Yasu the secondary(6.6%,11.0%,0,respectively)and to fluconazole the last(4.7%,7.4%,1.9%,respectively),and the rates of tolerance of Candida parapsilosis,Candida krusei,Candida Portugal,Candida lipolztica to amphotericin B,fluconazole,itraconazole,Fushita Yasu were all 0. Conclusion In ICU,the Candida infection is mainly in the respiratory tract and urinary tract,its rate of infection has a tendency of rising,and the rate of Candida tolerance to itraconazole is the highest.
ABSTRACT
Objective To investigate the effects and mechanism of prone ventilation in rats with lipopolysaccharide(LPS)-induced extra pulmonary acute lung injury(ALI). Methods Thirty-two male Sprague-Dawley(SD)rats were randomly divided into four groups:control group,ALI group,supine position group(ALIS group)and prone position group(ALIP group). The ALI animal model was reproduced by intra-peritoneal injection of LPS 6 mg/kg,and 2 mL/kg sterile saline was intra-peritoneally injected in control group. After 24 hours,the ALIS group and ALIP group were mechanically ventilated for 4 hours in supine and prone positions respectively. Arterial partial pressure of oxygen(PaO2),carbon dioxide partial pressure(PaCO2),wet to dry weight ratio of lung(W/D) were observed,and the levels of tumor necrosis factor-α(TNF-α),interleukins(IL-6,IL-10)in bronchoalveolar lavage fluid(BALF)were measured. The degrees of histopathological changes of lung were investigated and assessed under light microscope. Results Compared with control group,PaO2 was significantly lower in ALI,ALIS and ALIP groups〔mmHg(1 mmHg=0.133 kPa):68±7,82±8,93±7 vs. 116±7〕,and the PaCO2 in ALI and ALIS groups was obviously higher(mmHg:53±6,51±5 vs. 43±7,both P<0.05);lung W/D ratio as well as levels of TNF-α, IL-6 and IL-10 in BALF were significantly higher in ALI,ALIS and ALIP groups〔lung W/D ratio:5.11±0.32, 4.71±0.38,4.53±0.45 vs. 4.48±0.15,TNF-α(ng/L):548±82,431±64,347±53 vs. 162±16,IL-6(ng/L):772±119,587±178,490±139 vs. 127±16,IL-10(ng/L):211±43,295±36,352±59 vs. 104±31,all P<0.05〕. Compared with ALI group,PaO2 in ALIS and ALIP groups was significantly higher,and in ALIP group,PaCO2 was lower,lung W/D ratio,TNF-α and IL-6 in BALF were obviously lower,while IL-10 in BALF was obviously higher(all P<0.05). Compared with ALIS group,the changes in ALIP group were more significant(all P<0.05). Compared with ALIS group,under light microscope,it was shown that the hyper-inflated areas were less,normal and collapsed areas were greater on the ventral side,and the collapsed area was less and the normal ventilation area was greater on the dorsal side in ALIP group(all P<0.05). Conclusion In rats with LPS-induced extra pulmonary ALI,the prone ventilation can improve gas exchange,promote uniform distribution of ventilation,decrease pulmonary edema and in the mean time attenuate inflammatory response.
ABSTRACT
Objective To investigate the effects of electroacupuncture (EA) on the implementation of blind nasojejunal (NJ) tube placement and enteral nutrition (EN) in neurosurgical severe coma patients in intensive care unit (ICU).Methods Seventy-nine neurosurgical severe coma patients admitted to ICU were randomly divided into conventional group (blind NJ tube placement,n =40) and EA group (NJ placement and EA,n =39).EA was performed after NJ tube placement at bilateral acupoints Zusanli (ST36) and Hegu (L14) points using EA treatment instrument.The impelling distance of NJ tube were measured and the success rate of NJ tube placement were calculated.The postoperative complications were observed.Results The difference of NJ tube impelling distances at the 24th,48th,and 72th hours after surgery in EA group were significant longer than that in conventional group (P ＜ 0.05).The success rates of NJ tube placement at the 24th and 72nd hours after surgery in EA group were significantly better than that in conventional group (P ＜ 0.05).Their EN calories qualifiedness rate in 72 hours also increased significantly compared with conventional group and the proportion of patients assisted with parenteral nutrition decreased (P ＜0.05).The postoperative complications including alimentary tract hemorrhage,vomiting,and abdominal distension decreased remarkably in EA group compared with conventional group (P ＜ 0.05).Conclusions EA stimulation at acupoints could promote the gastrointestinal peristalsis of neurosurgical severe coma patients and elevate the success rate of blind NJ tube placement,so it is beneficial for the implementation of early enteral nutrition (EEN).
