ObjectiveTo explore the applicability of early goal-directed sedation (EGDS) in intensive care unit (ICU) patients with mechanical ventilation.MethodsAn prospective double blind study was conducted. ICU patients with mechanical ventilation in the First Affiliated Hospital of Jinzhou Medical University were recruited as research objects by chester sampling from September 2015 to September 2017, and divided into an experimental group and a control group by stratified randomization. Two groups were sedated on the basis of adequate analgesia. The experimental group adopted the EGDS strategy that dexmedetomidin was the first choice to be infused at the rate of 1 μg·kg–1·h–1. And the patients were given Richmond agitation-sedation score (RASS) on the interval of 4 hours: used additionally propofol and midazolam if RASS>2, or reduced right metomomidin at the speed of 0.2 μg·kg–1·h–1 per 30 min if RASS<–3, and stopped sedation until RASS of –2 to 0. The control group adopted routine sedation strategy that propofol was the first choice to be infused and combined with dexmedetomidine and midazolam until RASS score in –2 to –3. The doses of sedative drugs, mechanical ventilation time, ICU-stayed time, total hospitalization time and the incidence of adverse events such as delirium, accidental extubation, and ICU death were compared between two groups.ResultsSixty-sis cases were selected in the experimental group and 71 in the control group. The baseline data such as gender, age, acute physiology chronic health evaluation Ⅱ (APACHEⅡ), or basic diseases in two groups had no significant differences. Compared with the control group, the per capita total doses of dexmedetomidine, propofol and midazolam in the experimental group were significantly less [right metopromicine (μg): 154.45±27.86 vs. 378.85±39.76; propofol (mg): 4 490.03±479.88 vs. 7 349.76±814.31; midazolam (mg): 255.38±46.24 vs. 562.79±97.26; all P<0.01], mechanical ventilation time, ICU-stayed time, total hospitalization time were significantly lower [mechanical ventilation time (d): 7.7±3.3vs. 11.7±3.6; ICU-stayed time (d): 10.2±3.9 vs. 19.2±4.1, total hospitalization time (d): 29.9±4.6 vs. 50.4±9.1; all P<0.01]. The Kaplan-Meier survival curves showed that the incidence of delirium in the experimental group was significantly lower than that in the control group (log-rankχ2=5.481, P<0.05). The accidental extubation rate and accidental fatality rate in two groups had no significant differences (log-rankχ2=0.078, 0.999, P>0.05).ConclusionEGDS can not only reduce the dose of sedative drugs, shorten the mechanical ventilation time, the ICU-stayed time and the total hospitalization time, but also reduce the incidence of delirium, so it has a positive impact in ICU patients with mechanical ventilation.
Objective To evaluate the sedative and analgesic efficacy and adverse effect of dexmedetomidine versus propofol on the postoperative patients in intensive care unit (ICU). Methods The relevant randomized controlled trials (RCTs) were searched in The Cochrane Library, MEDLINE, PubMed, SCI, SpringerLinker, ScinceDirect, CNKI, VIP, WanFang Data and CBM from the date of their establishment to November 2011. The quality of the included studies was evaluated after the data were extracted by two reviewers independently, and then the meta-analysis was performed by using RevMan 5.1. Results Ten RCTs involoving 793 cases were included. The qualitative analysis results showed: within a certain range of dosage as dexmedetomidine: 0.2-2.5 μg/(kg·h), and propofol: 0.8-4 mg/(kg·h), dexmedetomidine was similar to propofol in sedative effect, but dexmedetomidine group needed smaller dosage of supplemental analgesics during the period of sedative therapy. The results of meta-analysis showed: the percentage of patients needing supplemental analgesics in dexmedetomidine group was less than that in propofol group during the period of sedative therapy (OR=0.24, 95%CI 0.08 to 0.68, P=0.008). Compared with the propofol group, the duration of ICU stay was significantly shorter in the dexmedetomidine group (WMD= –1.10, 95%CI –1.88 to –0.32, P=0.006), but the mechanical ventilated time was comparable between the two groups (WMD=0.89, 95%CI –1.15 to 2.93, P=0.39); the incidence of adverse effects had no significant difference between two groups (bradycardia: OR=3.57, 95%CI 0.86 to 14.75, P=0.08; hypotension: OR=1.00, 95%CI 0.30 to 3.32, P=1.00); respiratory depression seemed to be more frequently in propofol group, which however needed further study. Mortalities were similar in both groups after the sedative therapy (OR=1.03, 95%CI 0.54 to 1.99, P=0.92). Conclusion Within an exact range of dosage, dexmedetomidine is comparable with propofol in sedative effect. Besides, it has analgesic effect, fewer adverse effects and fewer occurrences of respiratory depression, and it can save the extra dosage of analgesics and shorten ICU stay. Still, more larger-sample, multi-center RCTs are needed to provide more evidence to support this outcome.
Objective To investigate the species distribution and antibiotic resistance of pathogens fromcatheter-related bloodstream infections ( CRBSI) in intensive care unit( ICU) , to provide evidence for the guidance of clinical rational administration.Methods A retrospective analysis was performed to review the microbiological and susceptibility test data of all CRBSI patients in ICU from January 2009 to December 2011. The patterns of antibiotic resistance among the top seven bacteria were compared. Results 67 cases of CRBSI were detected with 81 strains, including 40 Gram-positive ( G+ ) bacteria( 49.4% ) , 38 Gram-negative( G- ) bacteria ( 46.9% ) , and 3 fungi ( 3.7% ) . The main pathogens causing CRBSI were coagulase negative Staphylococci ( 27 strains, 33.3%) , Acinetobacter baumannii ( 12 strains, 14.8% ) , Klebsiella pneumoniae( 9 strains, 11. 1% ) , Staphylococcus aureus ( 8 strains, 9. 9% ) , Pseudomonas aeruginosa ( 7 strains, 8. 6% ) , Escherichia coli ( 6 strains, 7.4% ) , suggesting that Staphylococcus epidermidis was predominant pathogenic G+ bacteria, and Acinetobacter baumannii was predominant G- bacteria. The antibiotic resistance tests demonstrated that isolated G- bacillus was highly sensitive to carbopenem, while vancomycin-resistant G+ bacteria were not found. Conclusions Within the latest 3 years, the predominant pathogens of CRBSI in ICU are Staphylococcus epidermidis and Acinetobacter baumannii. Acinetobacter baumannii exhibited high drug resistance to all antibiotics.
ObjectiveTo explore the effect of early enteral nutrition (EEN) on immune status of patients in intenseive care unit (ICU). MethodsA prospective control study was conducted from July 2011 to December 2012, and 80 patients after trauma and surgery were admitted to ICU. The Patients were divided into EEN group and normal enteral nutrition (NEN) group randomly. Enteral nutrition in EEN group began within 24 hours after admitted to ICU, while within 48 hours in NEN group. ResultsIn 80 patients, 78(37 in EEN group and 41 in NEN group) completed the end point. The baseline in two groups was consistent (P>0.05). The indicators of lymphocyte, IgA, IgG, IgM and CD4+, CD8+, natural kill cell and pre-albumin values in EEN group were higher than those in NEN group (P<0.05). The incidence of diarrhea (8.1%, 26.8%) and infection of wound (2.7%, 17.1%) in EEN were less than those in NEN group. The hospitalization duration in ICU in EEN group[(7.94±3.72) days] was also shorter than that in NEN group[(10.62±3.14) days]. ConclusionEarly enteral nutrition improves immune function and nutrition status in ICU patients; it also protects gut barrier function and reduces the ICU hospitalization duration.
Objective To evaluate the clinical features and complications of bedside tracheal intubation in intensive care unit ( ICU) , and explore the suitable strategy of intubation. Methods In this retrospective study,42 patients who underwent bedside tracheal intubation in ICU during September 2008 and March 2009 were divided into a schedule group ( n =24) and an emergency group ( n =18) . The time to successful intubation, number of intubation attempts, and complications were recorded. The schedule group was defined as those with indications for intubation and fully prepared, while the emergency group was defined as those undergoing emergency intubations without full preparation due to rapid progression of disease and accidental extubation. Results The success rate for all patients was only 57. 1% on the first attempt ofintubation. The main complications during and after induction were hypotension ( 45. 2% ) and hypoxemia ( 50. 0% ) . Compared with the emergency group, the schedule group had fewer attempts to successful intubation ( 1. 71 ±1. 12 vs. 2. 67 ±1. 75) , higher success rate on the second attempt ( 87. 5% vs.61. 1%) , and lower ypoxemia incidence ( 29. 1% vs. 77. 8%, P lt; 0. 05) . Conclusions The tracheal intubation in ICU is a difficult and high risk procedure with obvious complications. Early recognition ofpatients with indications and well preparation are critical to successful bedside intubation.
ObjectiveTo systematically review the efficacy of ICU diaries on psychological outcomes, cognition and health-related quality of life in both patients and their relatives. MethodsThe PubMed, Embase, Web of Science, Cochrane Library, PsycINFO, CNKI, WanFang Data and VIP database were electronically searched to collect trails related to the objective from inception to August 2023. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.3 software. ResultsA total of 17 studies involving 2 093 patients and 786 relatives were included. The results of meta-analysis showed that compared with the control group, ICU diaries could improve patients’ post-traumatic stress disorder (PTSD) (RR=0.64, 95%CI 0.50 to 0.83, P<0.01), depression (RR=0.65, 95%CI 0.48 to 0.89, P<0.01) and quality of life (MD=7.78, 95%CI 4.37 to 11.18, P<0.01) significantly. However, there were no significant differences in patients’ anxiety, memory and relatives’ psychological outcomes. ConclusionCurrent evidence shows that the use of ICU diaries can reduce the incidence rate of patients’ PTSD, depression and improve their quality of life, but other effects are unclear. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To explore the type and frequency of oral care practice in intensive care units (ICUs) in Mainland China, and to provide evidence and suggestions for improving oral care practice. Methods Three survey methods, including mailing questionnaires to ICUs of Grade 3A hospitals, consulting experts in this field and visiting accessible ICUs, were used to survey current oral care practice in Mainland China. Results A total of 184 questionnaires were given to the subjects, of which 79 effective ones were collected, and the response rate was 42.93%. All 79 respondents considered oral care very unimportant, and 98.7% of the ICUs performed oral care in different ways. Currently, the cotton ball wipe-off method was the most frequently used for oral care (62.5%), with an average (9.1± 5.1) min per time, twice or three times daily. The mouthwashes often used were saline (76.1%), solutions containing sodium bicarbonate (22.8%), furacilin (13.9%), and hydrogen dioxide (13.9%). Conclusion The oral care practice for the critically-ill patients in ICUs of China is unsatisfactory, although it is perceived as an important item in nursing care. More evidence–based training should be given and it is necessary to establish a national oral care guideline for critically-ill patients.
Objective To investigate the characteristics of ventilator associated pneumonia (VAP)caused by Stenotrophomonas maltophilia(Sm)in ICU。Methods The clinical data of 39 patients with VAP caused by Sm，from Jan 2001 to Dec 2006，were retrospectively investigated．Results In 15 kinds of antibiotics sensitivity test，all cases showed 100％ resistance to 12 kinds of antibiotics except sulfamethoxazole／trimethoprim。ticarcillin／clavulanic acid and ciprofloxacin with sensitivity rate of 46．2％ ， 30．8％ and 12．8％ ．respectively．92．30％ of Sm VAP were CO—infected with other microorganisms and 79．5％ of VAP were late-onset．The use of broad-spectrum antibiotics．especially carbapenem．and prolonged mechanical ventilation more than 7 days were risk factors for Sm VAP．Morbidity of Sm VAP was 87．2％ ．Conclusions Sm VAP has an important role in ICU infections with high morbidity and CO-infection rate．It should be alerted to the possibility of Sm VAP in the case of when prolonged ventilation (gt;7 days)or carbapenem is used．
ObjectiveTo explore the safety of ventilator support in hyperbaric oxygen chamber and the prevention of related complications.MethodsFrom July 2016 to December 2018, there were 127 intensive care unit patients underwent hyperbaric oxygen therapy with ventilator. Medical professionals in hyperbaric medicine or intensive care medicine were arranged to accompany the patients in the treatment process, to observe the patients’ condition changes closely, monitor their heart rate, respiration, blood pressure, and oxygen saturation, and perform sputum suction at any time if needed and monitor the airway peak pressure change to prevent pneumothorax.ResultsDuring the process of hyperbaric oxygen therapy, 13 patients (10.24%) were treated with analgesia/sedation for patient-ventilator asynchrony, 4 patients (3.15%) exited the champer emergently for acute left heart failure, 3 patients (2.36%) had epileptic seizures, 3 patients (2.36%) had aspiration, and 1 patient (0.79%) had breath and cardiac arrest. After emergency treatment, all the patients returned to the ward safely.ConclusionDuring the treatment of hyperbaric oxygen therapy for intensive care unit patients with ventilator, the accompany of qualified professionals in hyperbaric medicine or intensive care medicine in the hyperbaric oxygen chamber can treat the patients’ symptoms timely and reduce the risk greatly.
Objective To investigate the postoperative treatment of pleuropneumonectomy for tuberculosis destroyed lung in ICU, in order to improve the therapeutical efficacy for these patients. Methods Clinical data of 52 patients who suffered from tuberculosis destroyed lung and underwent pleuropneumonectomy from June 2008 to June 2010 were analyzed retrospectively. All of subjects received routine treatment in ICU after the operation. Meanwhile，appropriate targeting treatments were applied including diagnosis and treatment of postoperative bleeding; application of fiberbronchoscope to aspirate the sputum after the operation,sequential non-invasive ventilation after the invasive ventilation for acute respiratory failure after operation ,etc.Results A total of 52 patients received the pleuropneumonectomy operation. Bleeding occurred in 11 cases after operation and stopped after the integrated therapy. 8 patients suffered from acute respiratory failure and attenuated after sequential ventilation. No patients died for postoperative bleeding or acute respiratory failure. Conclusions Patients who suffered from tuberculosis destroyed lung and received pleuropneumonectomy with postoperative bleeding and acute respiratory failure have a good prognosis after appropriate postoperative treatment in ICU.
