Metagenomic-based pathogen surveillance for children with severe pneumonia in pediatric intensive care unit.

Background: Pneumonia is a significant cause of morbidity and mortality in children. Metagenomic next-generation sequencing (mNGS) has the potential to assess the landscape of pathogens responsible for severe pulmonary infection. Methods: Bronchoalveolar lavage fluid (BALF) samples of 262 children with suspected pulmonary infections were collected from April 2019 to October 2021 in the Pediatric Intensive Care Unit (PICU) of Guangdong Women and Children Hospital. Both mNGS and conventional tests were utilized for pathogen detection. Results: A total of 80 underlying pathogens were identified using both mNGS and conventional tests. Respiratory syncytial virus (RSV), Staphylococcus aureus and rhinovirus were the most frequently detected pathogens in this cohort. The incidence rate of co-infection was high (58.96%, 148/251), with bacterial-viral agents most co-detected. RSV was the main pathogen in children younger than 6 months of age, and was also commonly found in older pediatric patients. Rhinovirus was prevalent in children older than 6 months. Adenovirus and Mycoplasma pneumoniae were more prevalent in children older than 3 years than in other age groups. Pneumocystis jirovecii was detected in nearly 15% of children younger than 6 months. Besides, influenza virus and adenovirus were rarely found in 2020 and 2021. Conclusions: Our study highlights the importance of using advanced diagnostic techniques like mNGS to improve our understanding of the microbial epidemiology of severe pneumonia in pediatric patients.

Fatigue and Quality of Life Among Patients with Diabetes and Non-diabetes Receiving Primary Percutaneous Coronary Interventions.

PURPOSE: Few studies have examined the effect of diabetes mellitus (DM) on patients with coronary artery disease. The relationships between quality of life (QoL), risk factors, and DM of patients receiving percutaneous coronary interventions (PCIs) are poorly understood. We investigated the influence of DM on fatigue and QoL over time among patients receiving PCIs. METHODS: An observational cohort study with a longitudinal, repeated-measures design was used to investigate fatigue and QoL among 161 Taiwanese patients with coronary artery disease with/without DM who received primary PCIs between February and December 2018. Participants provided demographic information and their Dutch Exertion Fatigue Scale and the 12-Item Short-Form Health Survey scores before the PCI and two weeks, three months, and six months post-discharge. RESULTS: Seventy-seven PCI patients were in the DM group (47.8%; mean age = 67.7 [SD = 10.4] years). The mean scores of fatigue, physical component scale (PCS), and mental component scale (MCS) were 7.88 (SD = 6.74), 40.74 (SD = 10.05), and 49.44 (SD = 10.57), respectively. DM did not affect the magnitude of change in fatigue or QoL over time. Patients with DM perceived similar fatigue as those without DM before PCI and two weeks, three and six months post-discharge. Patients with DM perceived lower psychological QoL than those without DM two weeks post-discharge. Compared to pre-surgery scores, patients without DM perceived lower fatigue at two weeks, three months, and six months post-discharge, and higher physical QoL at three- and six-months post-discharge. CONCLUSIONS: Compared with DM patients, patients without DM had higher pre-intervention QoL and better psychological QoL two weeks post-discharge, and DM did not influence fatigue or QoL of patients receiving PCIs over six months. DM may affect patients in the long term; therefore, nurses should educate patients to regularly take medication, maintain proper habits, notice comorbidities, and follow rehabilitation regimes after PCIs to improve prognosis.

A simple nanocomposite photocatalyst HT-rGO/TiO2 for deoxynivalenol degradation in liquid food.

A simple nanocomposite photocatalyst HT-rGO/TiO2 for deoxynivalenol (DON) degradation was synthesized by hydrothermal method to maintain the quality of cereal grains and byproducts. The characterization of HT-rGO/TiO2 was analyzed by XRD, FTIR, Raman spectroscopy, and XPS. Moreover, according to UV-vis DRS analysis, HT-rGO/TiO2 had a smaller band gap, indicating a wider response range to light and a higher utilized rate of quantum photons. Additionally, the results of LC-MS showed that the hydroxyl group at the C3 position, and the unsaturated bond between C9 and C10, and the epoxy group at C12 and C13 positions of DON molecule were destroyed step by step by photocatalytic degradation. These groups have active effects on the DON toxicity, which means it is successful to degrade DON in liquid-food by HT-rGO/TiO2 photocatalyst.

Effects of comprehensive geriatric care on depressive symptoms, emergency department visits, re-hospitalization and discharge to the same residence in older persons receiving hip-fracture surgery: A meta-analysis.

AIM: The aim of this study was to evaluate depressive symptoms, emergency department visits, re-hospitalization and discharge to the same residence of comprehensive geriatric care in patients receiving hip-fracture surgery. BACKGROUND: Hip fractures among older persons result in restricted activities of daily living, longer hospital stays, frequent emergency department visits and re-presentation to hospital, which may increase depressive symptoms and death risk. The benefits of comprehensive geriatric care have not been determined. DESIGN: A five-step Cochrane collaboration meta-analysis was used. DATA SOURCES: Randomized controlled trials published from 1980 to 2020 in which comprehensive geriatric care was provided following hip-fracture surgery were retrieved from the Cochrane Library, Clinical Key, Embase, MEDLINE, OVID and PubMed databases. Indicators were depressive symptoms, emergency department visits, re-hospitalization and discharge to the same residence. REVIEW METHODS: The Group Reading Assessment, Risk of Bias 2.0 tool, modified Jadad scale and Comprehensive Meta-Analysis Version 3 software were used. RESULTS: Overall, 1291 patients from six randomised controlled trials were included. Comprehensive geriatric care improved depressive symptoms and lowered emergency department visits but did not improve re-hospitalization rates or discharge to the same residence. CONCLUSION: Comprehensive geriatric care should include depression management and individualized care plans. Further depression-related studies are required to verify their benefits.

The effectiveness of acupressure for managing postoperative pain in patients with thoracoscopic surgery: A randomized control trial.

PURPOSE: More than 86% patients experience moderate to severe pain after thoracoscopic surgery. A combination of diverse nonpharmacological pain relief methods is a developing trend for pain management. The purpose of this study was to explore the effect of acupressure in reducing pain after thoracoscopic surgery. DESIGN: A Randomized controlled study with purpose sampling was used for this study. Patients who underwent thoracoscopic surgery at a medical center in central Taiwan were enrolled. Study data was collected from September 2020 to April 2021 after the approval of the institutional review board. A total of 100 participants were randomized into two groups (49 and 51 in the experimental and control groups, respectively). METHODS: Participants in the experimental group received acupressure at the Neiguan (PC6) and Shenmen (HT7) acupoints thrice a day for 2 days, whereas those in the control group received routine treatment and did not receive acupressure. The measurement included questionnaires for the collection of general information, physiological information, and disease rating scale. The Visual Analogue Scale-Pain (VAS-P) was used to measure the severity of pain. SPSS statistical software was used for data analysis. Independent sample t-test and chi-squared test were used for descriptive statistics, and paired t-test and linear mixed model were used to examine the effect of acupressure in alleviating pain. FINDINGS: After acupressure intervention, the pain score of the experimental group was lower than that of the control group, and this difference was significant ß = 17.76, p < 0.001 on day 1 after intervention; ß = 19.80, p < 0.001 on day 2 after intervention. The postoperative pain score in the experimental group on day 2 after intervention was significantly lower than that in the control group (t = 2.039, p = 0.044). After the subjects received acupressure, pain index significantly decreased after considering the interaction between time and group (p < 0.001). Regardless of the type of surgery, there were significant differences in pain index when the interaction between time and group was considered (p < 0.001). CONCLUSIONS: This study provided an experimental basis that acupressure can help in pain management in patients after thoracoscopic surgery, and the pain relief results become more significant as the duration of intervention increases. CLINICAL RELEVANCE: Acupressure is effective in relieving postoperative pain in any type of thoracoscopic surgery. Nurses can use acupressure to help control pain in patients after thoracoscopic surgery.

Self-Efficacy Care Program for Older Adults Receiving Hip-Fracture Surgery.

Hip fractures decrease older adults' physical activity and quality of life (QoL). However, no current self-efficacy care programs are managed by clinical nurses, and thus no studies have measured their effects on self-care self-efficacy (SCSE). Hence, this quasi-experimental study determined the effectiveness of a self-efficacy care program (SECP) in 104 older adults receiving hip-fracture surgery who were divided into intervention and control groups. The Strategies Used by People to Promote Health and Short Form-36 were administered pre-surgery and at 1 and 3-month intervals post-surgery. The SCSE and QoL of the SECP group were significantly better than the control group at 1- and 3-month follow-ups post-surgery. Both groups' QoL decreased at one-month post-surgery but increased by 3-months post-surgery. The SECP group had higher psychological QoL than the control group post-surgery. This intervention increased the SCSE and QoL of older adults with hip fractures and improved post-operative care.

Arrhythmia Perception and Quality of Life in Bradyarrhythmia Patients Following Permanent Pacemaker Implantation.

Although studies have evaluated the quality of life (QoL) of patients undergoing permanent pacemaker (PPM) placement, their results are inconsistent. To assess arrhythmia perceptions and QoL in bradyarrhythmia patients following PPM implantation, 137 patients completed demographic, arrhythmia perception, and QoL questionnaires before and six months after implantation. Before implantation, they reported fatigue (74.1%), dizziness (72.9%), dyspnea (64.7%), chest pain (62.4%), and heart fluttering (54.1%). After implantation, arrhythmia perceptions and QoL showed significant improvement (p < .05), except vitality (p > .05). However, patients with arrhythmia for more than three years, three or more PPM implants, two or more comorbidities, or were 41-50 years showed no significant QoL improvement. Doctors and hospital educators, rather than nurses, provided the most PPM information to patients. Since nurses provide primary in-hospital care to PPM patients, they should impart more patient education while considering individual characteristics in caring situations to enhance patients' QoL.

Music Interventions in Percutaneous Coronary Procedures: A Meta-Analysis.

To clarify the effectiveness of music intervention for improving the well-being of patients undergoing coronary procedures for coronary heart disease, we conducted full-text searches of various databases (MEDLINE, Cochrane Library, CINAHL, ProQuest, and Airiti Library; 1966-2019) to identify randomized controlled trials and quasi-experimental studies of music intervention in recipients of angiography or percutaneous coronary intervention. Outcome measures included anxiety, discomfort, pain, heart rate, and blood pressure. The Cochrane methodology, Jadad Quality Score, and ROBINS-I were employed to evaluate evidence from 10 studies. Music intervention reduced anxiety (effect size: Z = 2.15, p = .03; six studies) and discomfort of lying (Z = 2.40, p = .02; two studies), but did not affect pain (Z = 0.94; two studies), heart rate (Z = 0.94; five studies), or blood pressure (systolic, Z = 1.27; diastolic, Z = 1.32; four studies) (all p > .05). The heterogeneity among studies was high. Large-scale, transcultural, high-quality trials are warranted to confirm the benefit of music intervention in patients undergoing coronary procedures.

Value of ambroxol in the treatment of asthmatic bronchitis.

OBJECTIVE: To investigate the clinical effect of ambroxol in the treatment of asthmatic bronchitis. METHODS: One hundred and twenty patients with asthmatic bronchitis who were admitted to our hospital from June 2017 to August 2018 were selected as the research subjects and divided into a control group and an observation group according to random number table method, 60 in each group. The control group was treated with conventional treatment, while the observation group was treated with ambroxol in addition to conventional treatment. The therapeutic effect, disappearance time of symptoms and signs and the recovery of pulmonary function were compared between the two groups. RESULTS: The total effective rate of the observation group was 96.7%, and that of the control group was 73.3%. The control effect of the observation group was significantly better than that of the control group, showing a significant difference (P<0.05). The disappearance time of symptoms of the observation group was shorter than that of the control group, and the recovery of pulmonary function was better; the differences were statistically significant (P<0.05). CONCLUSION: For asthmatic bronchitis patients, addition of ambroxol to conventional treatment can improve the therapeutic effect, shorten the disappearance time of clinical signs and symptoms, and promote the recovery of patients, which is worth clinical application.

Meta-analysis: Effectiveness of Comprehensive Geriatric Care for Elderly Following Hip Fracture Surgery.

Hip fractures may increase mortality and decrease mobility in elderly patients. Effectiveness of comprehensive geriatric care (CGC) has not been verified. A systematic review and a meta-analysis were conducted by searching full-text databases (1988-2018) of Cochrane Library, Clinical Key, Embase, MEDLINE, CINAHL, and ProQuest for randomized controlled trials (RCTs) of CGC following hip fractures. Outcome measures were mortality, activities of daily living, hospital stay, and discharge to institutional setting. Cochrane RoB 2.0, Jadad Quality Score, and Group Reading Assessment were used for analysis. Of the 11 studies included, 8 examined mortality (effect size Z = 2.51, p = 0.01), 5 examined daily activities (effect size Z = 3.31, p = 0.0009), 7 examined length of hospital stay (effect size Z = 0.18, p = 0.85), and 5 examined discharged to an institutional setting (effect size Z = 0.81, p = 0.42). Results showed that CGC decreased mortality and improved daily living activities.

Effects of Lumbar Fusion Surgery with ISOBAR Devices Versus Posterior Lumbar Interbody Fusion Surgery on Pain and Disability in Patients with Lumbar Degenerative Diseases: A Meta-Analysis.

Purpose/Aim: Lumbar degenerative diseases (LDDs) cause pain and disability and are treated with lumbar fusion surgery. The aim of this study was to evaluate the efficacy of lumbar fusion surgery with ISOBAR devices versus posterior lumbar interbody fusion (PLIF) surgery for alleviating LDD-associated pain and disability. Materials and Methods: We performed a literature review and meta-analysis conducted in accordance with Cochrane methodology. The analysis included Group Reading Assessment and Diagnostic Evaluation assessments, Jadad Quality Score evaluations, and Risk of Bias in Non-randomized Studies of Interventions assessments. We searched PubMed, MEDLINE, the Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, ProQuest, the Airiti Library, and the China Academic Journals Full-text Database for relevant randomized controlled trials and cohort studies published in English or Chinese between 1997 and 2017. Outcome measures of interest included general pain, lower back pain, and disability. Results: Of the 18 studies that met the inclusion criteria, 16 examined general pain (802 patients), 5 examined lower back pain (274 patients), and 15 examined disability (734 patients). General pain, lower back pain, and disability scores were significantly lower after lumbar fusion surgery with ISOBAR devices compared to presurgery. Moreover, lumbar fusion surgery with ISOBAR devices was more effective than PLIF for decreasing postoperative disability, although it did not provide any benefit in terms of general pain or lower back pain. Conclusions: Lumbar fusion surgery with ISOBAR devices alleviates general pain, lower back pain, and disability in LDD patients and is superior to PLIF for reducing postoperative disability. Given possible publication bias, we recommend further large-scale studies.

Type D Personality, Social Support, and Depression Among Ethnic Chinese Coronary Artery Disease Patients Undergoing a Percutaneous Coronary Intervention: An Exploratory Study.

This study investigated the relationships between Type D personality, depression, and social support among ethnic Chinese coronary artery disease (CAD) patients undergoing percutaneous coronary interventions. Type D personality is associated with CAD, and may increase patients' depression and mortality rate. However, very few studies have explored the relationships between depression and social support among ethnic Chinese Type D CAD patients. A longitudinal, repeated-measures design was used; 105 Taiwanese CAD patients undergoing a percutaneous coronary intervention were recruited between January and December 2015. A demographic questionnaire, Type D Scale, ENRICHD Social Support Inventory, and Patient Health Questionnaire-9 were completed by 102 participants (mean age = 64.42, SD = 13.67 years) at hospitalization, and at the second week and third month after discharge. Data were analyzed using t tests and a generalized estimating equation. Results indicated that 46.7% of participants who had Type D personality had lower social support and higher depression than did the remaining (non-Type D) participants. At two weeks after discharge, the improvement in social support was higher among Type D patients than non-Type D participants; the same was true for depression at two weeks and three months after discharge each. Type D Taiwanese CAD patients showed lower perceived social support and higher depression during hospitalization than did non-Type D participants. Furthermore, the more social support patients received at home, the lower was their depression. Health-care providers should provide continuous mental health care, conduct early screening of mental health issues, and ensure that patients receive sufficient social support to reduce depression.

Safety and efficacy of using vascular closure devices for hemostasis on sheath removal after a transfemoral artery percutaneous coronary intervention.

AIM: To determine the efficacy of vascular closure devices (VCDs) for hemostasis following transfemoral percutaneous coronary interventions (PCIs). METHODS: This two-group pre-post-test observational study with purposive sampling enrolled 73 patients between January, 2014 and February, 2015. The patients were allocated to either the intervention (vascular closure devices group, n = 34) or the control group (manual compression [MC] group, n = 39). Questionnaires were used to assess their demographic and clinical characteristics, vascular complications, visual analogue scale score for pain, and discomfort levels. Pain and discomfort were measured before and after the PCI. RESULTS: Vascular complications were observed in 15 (44.1%) VCD patients and 13 (33.3%) MC patients, with no significant between-group difference. However, the VCD patients had a higher relative risk of bruising, hematomas, and need for further treatment. After the PCI, the pain scores and discomfort levels increased significantly in both groups, but the VCD patients had more successful hemostasis, less pain, and less physical and psychological discomfort (lower-limb numbness, shoulder pain, restlessness, and worrying about walking ability, being unable to lift heavy objects in the future, and taking time off from work). CONCLUSION: The VCDs seem to be superior to the MCs, providing more successful hemostasis, less pain and discomfort, and earlier ambulation after a transfemoral PCI. These findings aid clinical nurses in understanding the risk of vascular complications, discomfort, and pain that are associated with VCD use for improving the quality of clinical care and help clinicians in determining the appropriate hemostatic method for patients undergoing a transfemoral PCI, particularly in the Chinese population.

[Nursing Care of Patients With Carotid Artery Stenosis Who Receive Carotid Artery Stent].

Atherosclerosis, a major cause of carotid artery stenosis, has a high correlation to stroke, which may induce transient ischemic attack (TIA) and/or permanent brain damage. The main treatment of carotid artery stenosis includes medication, carotid endarterectomy (CEA), and carotid artery stenting (CAS). However, when artery stenosis becomes severe, CEA or CAS is the most-often recommended intervention. CAS, a type of revascularization, is considered less invasive than CEA and is associated with a higher successful rate. CAS not only treats carotid stenosis effectively and reduces the incidence of stroke and myocardial infarction but also may increase the survival rate. Because CAS may lead to in-stent restenosis, an eluting stent has been developed to prevent this adverse event. However, the effectiveness of the eluting stent has yet to be adequately verified. As patients who receive CAS remain at risk of recurrent stroke, intravascular restenosis, TIA, and mortality, post-procedure medical and nursing care for this population must be appropriately applied in order to maximize the rate of long-term success. Therefore, we recommend that clinical physicians and nurses regularly evaluate and monitor post-CAS patients in order to prevent complications. Moreover, they should educate patients before discharge on post-CAS wound care and medicine-taking regimens as well as on the importance of smoking cessation, controlling blood sugar and blood pressure, exercising regularly, reducing body weight, maintaining a healthy diet, and controlling the risk factors of atherosclerosis in order to prevent the recurrence of complications.

Age and pain as predictors of discomfort in patients undergoing transfemoral percutaneous coronary interventions.

BACKGROUND: Transfemoral percutaneous coronary intervention (PCI) requires strict bed rest, causing pain and discomfort in patients. However, no studies have investigated this issue. OBJECTIVES: To investigate the predictors of discomfort in transfemoral PCI patients. METHODS: A cross-sectional sample of 110 patients from two coronary care units completed questionnaires on demographic and clinical characteristics, visual analogue pain scale, and discomfort. RESULTS: Eight factors predicted overall discomfort: physiologic pain, physiological discomfort, psychological discomfort, analgesic use after sheath removal, hemostasis method, and bed rest duration. Psychological discomfort was associated with age, chronic obstructive pulmonary disease, analgesic use after sheath removal, successful hemostasis, and hematoma >5 cm. A hierarchical regression model explained 70.5% of the variance in overall discomfort. CONCLUSIONS: Age and physiologic pain are major predictors of overall discomfort, especially in patients aged <60 years having high pain sensitivity. Critical care providers should note patients' physiological and psychological issues throughout the PCI process.

Efficacy of forced-air warming for preventing perioperative hypothermia and related complications in patients undergoing laparoscopic surgery: A randomized controlled trial.

BACKGROUND: Perioperatively, unexpected hypothermia may cause adverse surgical outcomes. However, few studies have explored the efficacy of forced-air warming in patients undergoing laparoscopic surgery. AIM/OBJECTIVE: To determine the efficacy of forced-air warming for preventing perioperative hypothermia and complications in patients undergoing laparoscopic surgery. METHODS: A total of 127 participants undergoing laparoscopic thoracic or abdominal surgery were recruited between January and November 2015. Participants were randomly allocated to intervention (forced-air warming, n = 64) and control groups (passive insulation, n = 63). Oesophageal core temperature was measured during surgery, whilst tympanic core temperature was measured every 30 minutes preoperatively and in the postanaesthesia care unit. Levels of shivering and pain, amount of bleeding, and adverse cardiac events were measured before the transfer from the postanaesthesia care unit. The generalized estimating equation was used for data analysis. RESULTS: The intervention group had better warming efficacy than the control group between 90 and 330 minutes during surgery. The intervention group had fewer complications than the control group in terms of intraoperative bleeding, time to rewarm to 36°C, pain levels, and shivering levels in the postanaesthesia care unit. CONCLUSION: Forced-air warming can increase warming efficacy and reduce complications of perioperative hypothermia in patients undergoing laparoscopic surgery.

Social Support, Unstable Angina, and Stroke as Predictors of Depression in Patients With Coronary Heart Disease.

BACKGROUND: Depression is known to adversely affect coronary heart disease patients in western countries; however, no study of social support and depression has been conducted in the Chinese population. OBJECTIVE: The aim of this study was to investigate the predictors of depression in patients with coronary heart disease. METHODS: Between January and December 2015, a cross-sectional sample of 105 Taiwanese patients from cardiology units completed a demographic and clinical characteristics questionnaire, Enhancing Recovery in Coronary Heart Disease Social Support Inventory, and Patient Health Questionnaire-9. RESULTS: Thirty-nine percent of the participants reported low social support, and 61.0% had depression symptoms. Eight factors predicted depression. Social support was significantly and adversely correlated with depression (r = -.481, P < .01). The other 7 factors were positively correlated with depression: age (r = .212, P < .05), reported monthly income of less than US $600 (F = 4.98, P = .001), lack of exercise (F = 3.75, P = .027), history of stroke (t = -2.45, P = .016) and kidney disease (t = -2.41, P = .018), unstable angina (F = 3.56, P = .031), and groin puncture (F = 3.27, P = .042). A hierarchical regression model explained 43.7% of the variance in depression. CONCLUSION: Social support, unstable angina, and stroke may be important predictors of depression in patients with coronary heart disease. These findings help clinical staff to understand physical and mental health problems in cardiovascular patients. Thus, we suggest that early depression prediction and sufficient social support can help patients to face their disease and thus improve depression and health care quality.

The Medical Futility Experience of Nurses in Caring for Critically Ill Patients.

BACKGROUND: Medical futility is a key bioethical concern. In Taiwan, policymakers tend to provide care standards and evaluation guidelines for critically ill and terminal patients whose treatment is medically futile. However, the current status of medical futility for critically ill patients is inadequate, and no consensus currently exists on the definition of medical futility. PURPOSE: The aim of this study was to understand the medical futility experiences of intensive care nurses. METHODS: This qualitative research adopted a phenomenological perspective and was conducted in a medical center and a regional hospital in Central Taiwan. Eight nurses with at least 1 year of nursing tenure who were serving in the intensive care unit were recruited. Purposive and snowball sampling methods were used to conduct one-on-one in-depth interviews. Each of the tape-recorded interviews was transcribed before data analysis. RESULTS: The research results found four themes, including (a) definitions of medical futility and types of patients, (b) considerations of medical futility, (c) the occurrence of medical futility, and (d) nurses' responses to medical futility. The participants indicated that medical futility refers to the point at which the continued provision of treatment does not evidently ease the disease condition of a patient or improve his or her quality of life or when life-sustaining treatment is provided to patients to facilitate the process of death. CONCLUSIONS: This study revealed that the major challenge in clinical cases of medical futility is for physicians, nurses, and patients to communicate effectively together during times of rapid and unanticipated change in patient condition. Thus, events of medical futility may be preventable. Past cases of medical futility involving critically ill patients may serve as references for guiding clinical care, education, and related policy formulation.

Forced-Air Warming for Rewarming and Comfort Following Laparoscopy: A Randomized Controlled Trail.

We investigated the efficacy of a forced-air warming (FAW) system on postoperative rewarming and comfort in patients undergoing laparoscopic surgery. In this randomized controlled trial, a total of 127 participants were randomly divided into the FAW group ( n = 64) and control group ( n = 63). The esophageal temperature was measured every 30 min during surgery, and the tympanic temperature and comfort levels were measured preoperatively and in the postanesthesia care unit (PACU). Data analysis used the generalized estimating equation. We found that there was a lower incidence of postoperative hypothermia in the FAW group compared with the control group, as well as a higher body temperature between 30 and 180 min in the PACU, a shorter time for rewarming, and a higher comfort level. Taken together, these results suggest that FAW is an effective rewarming technique for laparoscopic patients during surgery and in the PACU that improves comfort levels.

Meta-analysis: effectiveness of forced-air warming for prevention of perioperative hypothermia in surgical patients.

AIM: The aim of this study was to evaluate the effectiveness of forced-air warming for preventing perioperative hypothermia. BACKGROUND: Perioperative hypothermia commonly occurs in patients receiving anaesthesia during surgeries. However, the effectiveness of warming systems requires verification. DESIGN: Systematic review incorporating meta-analysis. DATA SOURCES: We searched OVID, PubMed, Cochrane Library, Medline, CINAHL, CETD and CEPS databases (2001-2015) for randomized controlled trials published in English and Chinese. Outcome measures of interests were body temperature and thermal comfort. REVIEW METHODS: Cochrane methods, Quality of evidence (GRADE) assessments and Jadad Quality Score were used. RESULTS: Twenty-nine trials (1875 patients) met inclusion criteria, including seven trials (502 patients) related to thermal comfort. Results showed that: (1) forced-air warming was more effective than passive insulation and circulating-water mattresses; (2) there was no statistically significant difference among forced-air warming, resistive heating blankets, radiant warming systems and circulating-water garments; and (3) that thermal comfort provided by forced-air warming was superior to that of passive insulation, resistive heating blankets and radiant warming systems, but inferior to that of circulating-water mattresses. CONCLUSIONS: Forced-air warming prevents perioperative hypothermia more effectively than passive insulation and circulating-water mattresses, whereas there is no statistically significant difference in its effectiveness compared with circulating-water garments, resistive heating blankets and radiant warming systems.
