Li W, Qian J, Liu X, Zhang Q, Wang L, Chen D, Lin Z. Management of severe crush injury in a front-line tent ICU after 2008 Wenchuan earthquake in China: an experience with 32 cases. Crit Care 2009; 13:R178. [PMID: 19895693 PMCID: PMC2811944 DOI: 10.1186/cc8160] [Citation(s) in RCA: 64] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2009] [Revised: 10/04/2009] [Accepted: 11/06/2009] [Indexed: 02/05/2023] Open
Abstract
INTRODUCTION The experience on management of crush injury after a devastating earthquake is lacking, and there are even less reports on the front-line critical care of these patients. A front-line intensive care unit (ICU) was set up in a tent after the disastrous Wenchuan earthquake (May, 12, 2008, China), where 32 patients suffering from crush injury were treated from May 12 to May 26. This study summarized our experience on management of 32 crush injury patients in a front-line tent ICU. METHODS We retrospectively analyzed the clinical data of 32 crush injury patients treated in our frontline tent ICU. Using limited equipment, we observed the arterial blood gas parameters, blood routine, alanine aminotransferase, lactate dehydrogenase, creatine kinase, creatinine, blood urea nitrogen, and urine protein of patients. We also closely watched for changes in crush injury symptoms, urine output, and the dangerous complications of crush injury. RESULTS Eighteen of the 32 patients developed traumatic shock, 9 had acute renal failure, 6 had acute heart failure, 2 had stress ulcers and 4 had multiple organ dysfunction syndrome (MODS). The symptoms of 17 patients met the criteria of crush syndrome; hemodialysis and prompt surgical intervention were given to them when necessary. Prompt treatment in our tent ICU improved the symptoms of patients to different degrees. The limb distension and sensory dysfunction were improved and the urine output was increased or even restored to the normal level in some patients. Serological parameters were improved in most patients after admission. Five (15.63%) patients underwent amputation due to severe infection in our group. Six (18.75%) patients died, 4 due to MODS and 2 due to acute renal failure. CONCLUSIONS Severe crushing injuries and life-threatening complications are major causes of death after major disasters like earthquakes. Prompt treatment and close monitoring of the severe complications are of great importance in saving patients' lives. Establishment of a well-equipped front-line ICU close to the epicentre of the earthquake allows for prompt on the spot rescue of critical patients with crush injury, greatly decreasing the mortality rate and complications and avoiding amputation. There should be sufficient equipment to meet the needs of more patients.

Abstract
OBJECTIVE To examine the impact of Hurricane Katrina on the health of individuals with diabetes. RESEARCH DESIGN AND METHODS This was an observational study in 1,795 adults with an A1C measurement 6 months before and 6-16 months after Hurricane Katrina in three health care systems: private (Tulane University Hospital and Clinic [TUHC]), state (Medical Center of Louisiana at New Orleans [MCLNO]), and Veterans Affairs (VA). Glycemic control (A1C), blood pressure, and lipids before the hurricane were compared with the patients' first measurement thereafter. The CORE Diabetes Model was used to project life expectancy and health economic impact. RESULTS Mean predisaster A1C levels differed between MCLNO and VA patients (mean 7.7 vs. 7.3%, P < 0.001) and increased significantly among MCLNO patients to 8.3% (P < 0.001) but not among VA and TUHC patients. Mean systolic blood pressure increased in all three systems (130-137.6 mmHg for TUHC and 130.7-143.7 for VA, P < 0.001; 132-136 for MCLNO, P = 0.008). Mean LDL cholesterol increased in the VA (97.1-104.3 mg/dl) and TUHC patients (103.4-115.5; P < 0.001). Hurricane Katrina increased modeled direct, indirect, and total health care costs and also reduced life expectancy as well as quality-adjusted life expectancy, with the economic impact being quite substantial because of the large population size affected. We estimate a lifetime cost of USD $504 million for the adult population affected, with the largest economic impact seen among MCLNO patients. CONCLUSIONS A major disaster had a significant effect on diabetes management and exacerbated existing disparities. These effects may have a lasting impact on both health and economic implications.

Abstract
A major earthquake struck the Niigata Prefecture, Japan, on October 23, 2004. This study investigated the effect of the earthquake on morning home blood pressure (MHBP) measurements, as well as clinic blood pressure (CBP) and associated complications, in 222 type 2 diabetic patients who measured MHBP and CBP before the earthquake. Physical and laboratory examinations were assessed at every three months. Each patient completed a questionnaire on MHBP measurement, Japanese intensity grade (JIS), patient's lifestyle and psychological impact using posttraumatic stress disorder (PTSD) symptom score. Median JIS showed all patients lived in areas affected by strong aftershocks. Most patients stayed in their own houses, while one-third of patients sought refuge in other houses. No new clinical manifestations of disease were noted. Median PTSD score was low. Patients in public refuge houses had daytime blood pressure, but MHBP was not measured. In the first month, the number of patients who continued MHBP measurements decreased to 27% of pre-shock level. Many patients were unable to measure MHBP for several reasons, including losing MHBP equipment, having equipment destroyed, or suffering from anxiety due to the extensive devastation. Mean systolic MHBP and median urinary albumin excretion rate (UAER) increased significantly within three months and returned to pre-earthquake level at six months. On multiple regression analysis, increased systolic and diastolic MHBPs were significantly associated with UAER elevation. In type 2 diabetic patients following an earthquake, it is important to develop a device of MHBP measurement for maintaining control of MHBP to prevent vascular complications.

Abstract
BACKGROUND Although acute coronary syndrome (ACS) and stroke are known to increase after earthquake, few data exist regarding the effect of earthquake on these cardiovascular events in rural areas. METHODS AND RESULTS The Noto Peninsula earthquake with a magnitude of 6.9 occurred at 9:45 a.m. on 25 March 2007. The first case of ACS occurred approximately 15 min later, whereas cerebral hemorrhage (CH) occurred 72 h after the onset of earthquake. During the 35 days after earthquake, among 49 patients who were attended by local ambulance, 5 patients with ACS (10.2%) and 8 with CH (16.3%) were documented and 4 died. The total number of both ACS and CH cases was greater than the averages for the same period of the past 3 years in this area (2.0 vs 5 and 2.3 vs 8, P<0.01). Interestingly, the most cases of ACS had occurred within 7 days after earthquake and for CH not until 35 days later. CONCLUSIONS Even in rural areas a severe earthquake results in increased incidence of ACS and CH, which can occur at different times after the event, although the effects of other environmental factors should be further investigated.

Abstract
BACKGROUND Inadequately controlled chronic diseases may present a threat to life and well-being during the emergency response phase of disasters. Chronic disease exacerbations (CDE) account for one of the largest patient populations during disasters, and patients are at increased risk for adverse outcomes. OBJECTIVE The objective of this study was to assess the burden of chronic renal failure, diabetes, and cardiovascular disease during disasters due to natural hazards, identify impediments to care, and propose solutions to improve the disaster preparation and management of CDE. METHODS A thorough search of the PubMed, Ovid, and Medline databases was performed. Dr. Miller's personal international experiences treating CDE after disasters due to natural hazards, such as the 2005 Kashmir earthquake, are included. DISCUSSION Chronic disease exacerbations comprise a sizable disease burden during disasters related to natural hazards. Surveys estimate that 25-40% of those living in the regions affected by hurricanes Katrina and Rita lived with at least one chronic disease. Chronic illness accounted for 33% of visits, peaking 10 days after hurricane landfall. The international nephrology community has responded to dialysis needs by forming a well-organized and effective organization called the Renal Disaster Relief Task Force (RDRTF). The response to the needs of diabetic and cardiac patients has been less vigorous. Patients must be familiar with emergency diet and renal fluid restriction plans, possible modification of dialysis schedules and methods, and rescue treatments such as the administration of kayexalate. Facilities may consider investing in water-independent extracorporeal dialysis techniques as a rescue treatment. In addition to patient databases and medical alert identification, diabetics should maintain an emergency medical kit. Diabetic patients must be taught and practice the carbohydrate counting technique. In addition to improved planning, responding agencies and organizations must bring adequate supplies and medications to care for diabetic, cardiac, and renal patients during relief efforts. CONCLUSIONS By recognizing and addressing impediments to the care of chronic disease exacerbations after natural disasters, the quality, delivery, and effectiveness of the care provided to diabetic patients during relief efforts can be improved.

Abstract
OBJECTIVE To investigate the occurrence of adverse blood pressure (BP) events during transurethral microwave therapy (TUMT) for benign prostatic hyperplasia. PATIENTS AND METHODS We conducted a retrospective study of the vital signs of 185 consecutive patients who received TUMT (via 6 devices) at 4 institutions from March 1, 2003, to September 18, 2005. Maximum change, percent change in systolic BP, diastolic BP, mean arterial pressures, heart rate, and oxygen saturation were evaluated. RESULTS Of the 185 patients, 77 patients (42%; 95% confidence interval [CI], 35%-49%) experienced an increase in systolic BP of more than 30 mm Hg during TUMT; 30 patients (16%; 95% CI, 12%-22%), an increase of more than 50 mm Hg; and 10 patients (5%; 95% CI, 3%-10%), an increase of more than 70 mm Hg. A greater than 20% change in systolic BP from baseline was observed in 95 patients (51%; 95% CI, 44%-58%). Many men experienced multiple events, with an average time of onset of 15.9 minutes into treatment. Significant differences were noted among the devices. CONCLUSION This retrospective study demonstrates a significant number of BP surges during TUMT for benign prostatic hyperplasia. These BP changes represent a potential risk of cardiovascular events in patients with known or occult cardiovascular disease. Our study is the first to recognize the incidence of this BP response. Until further studies identify the mechanisms responsible for these surges in BP, the results of this study suggest that BP should be monitored, treatment adjusted, and antihypertensive medications continued during all TUMT.

Abstract
BACKGROUND Prolonged physiological activation before or after stressors has gained recognition as a decisive element in theories that explain the link between stress and disease, specifically cardiovascular (CV) disease. This view is opposed to the conventional reactivity hypothesis that emphasizes responses during stressors. PURPOSE Prolonged activity has not often been an explicit research goal of real-life stress studies. Nevertheless, a growing number of these studies have provided evidence for prolonged activity, often as a secondary research goal. METHODS An overview of this evidence is lacking and is provided in this article. RESULTS The combined data from the reviewed studies suggest that discrete and chronic stress sources, as well as negative emotional episodes and dispositions, are related to prolonged CV activity of various durations, including sleep periods. On the other hand, evidence supporting the assumption that prolonged stress-related activation predicts disease is still very modest. CONCLUSIONS In this article we suggest that future research of prolonged activation should give priority to (a) the establishment of clear beginnings and endings of stressful events, (b) the prediction of disease by prolonged activation, and (c) potential psychological mediators of stress-related prolonged activation. These mediators may include, for example, worry and rumination, or other processes characterized by perseverative cognition, including unconscious processes.

Abstract
BACKGROUND Effects of catastrophic stress on blood pressure are well documented, but usually few measurements were taken before the event occurred, and the people studied were directly involved or geographically close to the disaster. The impact of the 11 September 2001 (9/11) attacks in New York City had far greater reach, and has been sustained by subsequent events. OBJECTIVE To test the hypothesis that, after the 9/11 attacks, blood pressures in the population affected would be increased compared with that in both the preceding months and the same period during the previous year. METHODS We used data available from a current study of blood pressure in four sites in the USA that enabled us to examine them from two perspectives: a mixed (within and between groups) analysis that tested the overall differences in blood pressure before and after 9/11, and a within-subjects model to examine the more focused issue of individual change in blood pressure after 9/11. The blood pressures of 427 hypertensive individuals were telemonitored at four sites. An additional 101 patients had been monitored at two sites during the same period in the previous year. RESULTS Mean systolic blood pressure was significantly greater during the 2 months after 9/11, across the four sites, compared with that assessed during the previous 2 months (range of observed differences 1.7-3.8 mmHg). At the two sites for which data were available for the same period in the year 2000, there was also a significant effect for the same period during the preceding year for systolic blood pressure. However, at both these sites the effect at 2000 was significantly smaller than the effect at 2001. Blood pressure also generally increased among those individuals in whom monitoring overlapped the 9/11 event. CONCLUSION The World Trade Center attacks produced a substantial and sustained increase in blood pressure that appears to be independent of seasonal effects, and which has important implications for morbidity and financial burden. The ubiquitous continuing reference to the events in the news reports may contribute to the sustained effects.

Abstract
The authors evaluated the effect of stress due to the Ji-Ji, Taiwan, earthquake, which occurred at 1:47 a.m. on September 21, 1999, on the onset of acute myocardial infarction in six counties near the earthquake epicenter. The rate of hospitalization due to acute myocardial infarction increased during the 6 weeks after the earthquake, and a significantly higher number of patients were hospitalized with acute myocardial infarction during that period, compared with the same 6-week period in the previous year (99 and 65 patients, respectively). The findings suggest that extreme emotional stress due to the natural disaster, superimposed on the stress of awakening, increased the incidence of acute myocardial infarction in this population.

Abstract
To examine the short- and long-term influences of the Marmara earthquake, which occurred on August 17, 1999 in Turkey, on glycemic control and quality of life (QOL), HbA1c, insulin requirement and QOL of 88 people with type 1 diabetes living in the quake zone were evaluated one year before (PreE), 3 months after (PostE) and one year after (FE) the earthquake. HbA1c levels and daily insulin requirements increased significantly at PostE (HbA1c from 7.4 +/- 1.3% to 8.5 +/- 1.8%, p<0.05; insulin from 0.58 +/- 0.2 IU/kg/day to 0.77 +/- 0.2 IU/kg/day, p<0.05). Mean total QOL scores at PostE were significantly lower than the scores obtained at PreE (62.7 +/- 17.3 vs 74.2 +/- 13.4, p<0.001). There were no significant differences between HbA1c levels and total QOL scores at PreE and FE. People with type 1 diabetes living in the same house after the earthquake and not having enough food supply were reported to have lower QOL than people moving to another house and having enough food supply after the earthquake (p = 0.014, p<0.0001, respectively). The Marmara Earthquake had a negative impact on the glycemic control and QOL of the subjects with type 1 diabetes for the short term but prequake scores might be achieved after a long period.

Abstract
Cardiovascular events occur most frequently in the morning. The morning surge in blood pressure may be associated with hypertensive target organ damage and subsequent cardiovascular risk in hypertensive patients. In our prospective study on elderly hypertensive patients, the morning blood pressure surge (defined as the increase from the lowest blood pressure during sleep to the average of the first 2 h after waking) was significantly associated with silent hypertensive cerebrovascular disease and subsequent stroke risk. This association was independent of age and 24-h ambulatory blood pressure levels. In addition, even after controlling for these factors and status of silent cerebrovascular disease, the contribution of the morning blood pressure surge remained significant, and a 10 mmHg increase in systolic morning blood pressure surge increase the stroke risk by 22%. A related factor is orthostatic hypertension, which might be associated with increased sympathetic activity, and which is significantly associated with an increase in morning blood pressure surge and ambulatory blood pressure variability. A possible implication is that, in addition to strict blood pressure control, antihypertensive medication that targets exaggerated morning blood pressure may achieve more effective prevention of cardiovascular events in hypertensive patients.

Abstract
There is growing evidence that stress contributes to cardiovascular disease. Chronic stress contributes to the atherosclerotic process through increased allostatic load, which is mediated by the neuroendocrine and immune systems (sympathetic nervous system and hypothalamus-pituitary adrenal axis) and related chronic risk factors (insulin resistance syndrome, hypertension, diabetes, and hyperlipidemia). In addition, acute stress can trigger cardiovascular events predominantly through sympathetic nervous activation and potentiation of acute risk factors (blood pressure increase, endothelial cell dysfunction, increased blood viscosity, and platelet and hemostatic activation). Earthquakes provide a good example of naturally occurring acute and chronic stress, and in this review we focus mainly on the effects of the Hanshin-Awaji earthquake on the cardiovascular system. The Hanshin-Awaji earthquake resulted in a 3-fold increase of myocardial infarctions in people living close to the epicenter, particularly in women, with most of the increase occurring in nighttime-onset events. There was also a near doubling in the frequency of strokes. These effects may be mediated by changes in hemostatic factors, as demonstrated by an increase of D-dimer, von Willebrand factor, and tissue-type plasminogen activator (tPA) antigen. Blood pressure also increased after the earthquake, and was prolonged for several weeks in patients with microalbuminuria.
