RESUMO
INTRODUCTION: The American Academy of Pediatrics (AAP) guidelines recommend that children ≤12-years-old with height < 145 cm should use safety/booster seats. However, national adherence and clinical outcomes for eligible children involved in motor vehicle collisions (MVCs) are unknown. We hypothesized that children recommended to use safety/booster seats involved in MVCs have a lower rate of serious injuries if a safety/booster seat is used, compared to children without safety/booster seat. METHODS: This retrospective cohort study queried the 2017-2019 Trauma Quality Improvement Program database for patients ≤12-years-old and <145 cm (recommendation for use of safety/booster seat per American Academy of Pediatrics) presenting after MVC. Serious injury was defined by abbreviated injury scale grade ≥3 for any body-region. High-risk MVC was defined by authors in conjunction with definitions provided by the Centers for Disease Control and Prevention and the American College of Surgeons Committee on Trauma. RESULTS: From 8259 cases, 41% used a safety/booster seat. There was no difference in overall rate of serious traumatic injuries or mortality (both p > 0.05) between the safety/booster seat and no safety/booster seat groups. In a subset analysis of high-risk MVCs, the overall use of safety/booster seats was 56%. The rate of serious traumatic injury (53.6% vs. 62.1%, p = 0.017) and operative intervention (15.8% vs. 21.6%, p = 0.039) was lower in the safety/booster seat group compared to the no safety/booster seat group. CONCLUSIONS: Despite AAP guidelines, less than half of recommended children in our study population presenting to a trauma center after MVC used safety/booster seats. Pediatric patients involved in a high-risk MVC suffered more serious injuries and were more likely to require surgical intervention without a safety/booster seat. A public health program to increase adherence to safety/booster seat use within this population appears warranted.

INTRODUCTION: Isolated sternal fractures (ISFs) often result from deceleration or chest wall trauma. Current guidelines recommend screening ISF patients for blunt cardiac injury (BCI) with electrocardiogram (ECG) and troponin. If either is abnormal, 24-h telemetry monitoring is recommended. This study sought to determine if ISF patients with abnormal ECG will manifest any cardiac-related complications within 6 h of hospital arrival. METHODS: A retrospective study was performed at a single level I trauma center. Patients with diagnosed sternal fracture and an Abbreviated Injury Scale <2 for head/neck, face, abdomen, and extremities were included. Patients with multiple rib fractures or hemopneumothorax were excluded. Demographic data, ECG, troponin, and echocardiogram results were collected. The primary outcome was cardiac-related complications or procedures. Complications included hypotension, arrhythmia, and hemodynamic instability. Procedures included sternal stabilization, cardiac catheterization, or sternotomy/thoracotomy. Descriptive statistics were performed. RESULTS: One hundred twenty-nine ISF patients were evaluated, 68 (52.7%) had an ECG abnormality. Eight patients had elevated troponin (6.2%). One patient (0.78%) suffered a cardiac-related complication (arrhythmia); however, this was 82 h into hospitalization. Two patients suffered noncardiac complications (urinary tract infection and acute kidney injury) (1.55%). Three patients had echocardiogram abnormality (2.33%), but no patients sustained a BCI or underwent a BCI-related procedure. CONCLUSIONS: After ISF, <1% of patients suffered a cardiac-related complication and none had BCI. These findings suggest 24-h monitoring for patients with ISF and abnormal ECG may be unnecessarily long. A prospective multicenter study to evaluate the validity of these results is needed prior to change of practice.

Introduction: Long guns (LGs) are uniquely implicated in firearm violence and mass shootings. On 1/1/2019 California (CA) raised the minimum age to purchase LGs from 18 to 21. This study aimed to evaluate the incidence of LG violence in CA vs. Texas (TX), a state with rising firearm usage and fewer LG regulations, hypothesizing decreased LG firearm incidents in CA vs increased rates in TX after CA LG legislation. Methods: A retrospective analysis of the Gun Violence Archive (2015-2021) was performed. An additional analysis of all firearm incidents within TX and CA was performed. CA and TX census data were used to calculate incidents of LG violence per 10,000,000 people. The primary outcome was the number of LG-related firearm incidents. Median yearly rates of LG violence per 10,000,000 people were compared for pre (2015-2018) vs post (2019-2021) CA LG legislation (Senate Bill 1100 (SB1100). Results: Median LG incidents decreased in CA post-SB1100 (4.21 vs 1.52, p < 0.001) by nearly 64 %, whereas any gun firearm violence was similar pre vs post-SB1100 (77.0 vs 74.5 median incidents, p = 0.89). In contrast, median LG incidents increased after SB1100 (4.34 vs 5.17 median incidents, p = 0.011) by nearly 35 % in TX, with any gun incidents increasing by nearly 53 % (83.48 vs 127.46, p < 0.001). Conclusion: CA LG firearm incidents decreased following SB 1100 legislation whereas the incidence in TX increased during this same time. Meanwhile, the incidence of any firearm violence remained similar in CA but increased in TX. This suggests the sharp decline in CA LG incidents may be related to SB1100. Accordingly, increasing the age to purchase a LG from 18 to 21 at a federal level may help curtail LG violence nationally.
RESUMO
BACKGROUND: The Abbreviated Injury Scale (AIS) is widely utilized for body region-specific injury severity. The AAST-Organ Injury Scale (AAST-OIS) provides organ-specific injury severity but is not included in trauma databases. Previous researchers have used AIS as a surrogate for OIS. This study aims to assess AIS-abdomen concordance with AAST-OIS grade for liver and spleen injuries, hypothesizing concordance in terms of severity (grade of OIS and AIS) and patient outcomes. STUDY DESIGN: This retrospective study (7/2020-6/2022) was performed at three trauma centers. Adult trauma patients with AAST-OIS grade III-V liver and/or spleen injury were included. AAST-OIS grade for each organ was compared to AIS-abdomen by evaluating the percentage of AAST-OIS grade correlating with each AIS score as well as rates of operative intervention for these injuries. Analysis was performed with Chi-square tests and univariate analysis. RESULTS: Of 472 patients, 274 had liver injuries and 205 had spleen injuries grades III-V. AAST-OIS grade III-V liver injuries had concordances rates of 85.5%, 71% and 90.9% with corresponding AIS 3-5 scores. AAST-OIS grade III-V spleen injuries had concordances rates of 89.7%, 87.8% and 87.3%. There was a statistical lack of concordance for both liver and spleen injuries (both p<0.001). Additionally, there were higher rates of operative intervention for AAST-OIS grade IV and V liver injuries and grade III and V spleen injuries versus corresponding AIS scores (p<0.05). CONCLUSION: AIS should not be used interchangeably with OIS due to lack of concordance. AAST-OIS should be included in trauma databases to facilitate improved organ injury research and quality improvement projects.
RESUMO
Background: Despite the high prevalence of post-operative fever, a variety of approaches are taken as to the components of a fever evaluation, when it should be undertaken, and when empiric antibiotic agents should be started. Hypothesis: There is a lack of consensus surrounding many common components of a post-operative fever evaluation. Patients and Methods: The Surgical Infection Society membership was surveyed to determine practices surrounding evaluation of post-operative fever. Eight scenarios were posed in febrile (38.5°C), post-operative general surgery or trauma patients, with 19 possible components of work-up (physical examination, complete blood count [CBC], fungal biomarkers, lactate and procalcitonin [PCT] concentrations, cultures, imaging) and management (antibiotic agents). Each scenario was then re-considered for intensive care unit (ICU) patients (intubated/unstable hemodynamics). Agreement on a parameter (<1/4 or >3/4 of respondents) achieved consensus, positive or negative. Parameters between had equipoise; α was set at 0.05. Results: Among the examined scenarios, only CBC and physical examination received positive consensus across most scenarios. Blood/urine cultures, imaging, lactate, inflammatory biomarkers, and the empiric administration of antibiotic agents did not reach consensus; support was variable depending on the clinical scenario, illness severity, and the individual preferences of the answering clinician. The qualitative portion of the survey identified "fever threshold and duration," "clinical suspicion," and "physiologic manifestation" as the most important factors for deciding about the initiation of a fever evaluation and the potential empiric administration of antibiotic agents. Conclusions: There is consensus only for physical and examination routine laboratory work when initiating the evaluation of febrile post-operative patients. However, there are multiple components of a fever evaluation that individual respondents would select depending on the clinical scenario and severity of illness. Parameters demonstrating equipoise are potential candidates for formal guidance or pragmatic prospective trials.

INTRODUCTION: Traumatic brain injury (TBI) causes significant morbidity and mortality in pediatric patients and care is highly variable. Standardized mortality ratio (SMR) summarizes the mortality rate of a specific center relative to the expected rates across all centers, adjusted for case-mix. This study aimed to evaluate variations in SMRs among pediatric trauma centers for TBI. METHODS: Patients aged 1-18 diagnosed with TBI within the National Trauma Data Bank (NTDB) from 2017 to 2019 were included. Center-specific SMRs and 95% confidence intervals identified centers with mortality rates significantly better or worse than the median SMR for all centers. RESULTS: 316 centers with 10,598 patients were included. SMRs were risk-adjusted for patient risk factors. Unadjusted mortality ranged from 16.5 to 29.5%. Three centers (1.5%) had significantly better SMR (SMR <1) and three centers (1.5%) had significantly worse SMR (SMR >1). Significantly better centers had a lower proportion of neurosurgical intervention (2.4% vs. 11.8%, p < 0.001), a higher proportion of supplemental oxygen administration (93.7% vs. 83.5%, p = 0.004) and venous thromboembolism prophylaxis (53.2% vs. 40.6%, p < 0.001) compared to significantly worse centers. CONCLUSIONS: This study identified centers that have significantly higher and lower mortality rates for pediatric TBI patients relative to the overall median rate. These data provide a benchmark for pediatric TBI outcomes and institutional quality improvement. LEVEL OF EVIDENCE: Level III. TYPE OF STUDY: Retrospective Comparative Study.

BACKGROUND: Pregnant trauma patients (PTPs) undergo observation and fetal monitoring following trauma due to possible fetal delivery (FD) or adverse outcome. There is a paucity of data on PTP outcomes, especially related to risk factors for FD. We aimed to identify predictors of posttraumatic FD in potentially viable pregnancies. METHODS: All PTPs (≥18 years) with ≥24-weeks gestational age were included in this multicenter retrospective study at 12 Level-I and II trauma centers between 2016 and 2021. Pregnant trauma patients who underwent FD ((+) FD) were compared to those who did not deliver ((-) FD) during the index hospitalization. Univariate analyses and multivariable logistic regression were performed to identify predictors of FD. RESULTS: Of 591 PTPs, 63 (10.7%) underwent FD, with 4 (6.3%) maternal deaths. The (+) FD group was similar in maternal age (27 vs. 28 years, p = 0.310) but had older gestational age (37 vs. 30 weeks, p < 0.001) and higher mean injury severity score (7.0 vs. 1.5, p < 0.001) compared with the (-) FD group. The (+) FD group had higher rates of vaginal bleeding (6.3% vs. 1.1%, p = 0.002), uterine contractions (46% vs. 23.5%, p < 0.001), and abnormal fetal heart tracing (54.7% vs. 14.6%, p < 0.001). On multivariate analysis, independent predictors for (+) FD included abdominal injury (odds ratio [OR], 4.07; confidence interval [CI], 1.11-15.02; p = 0.035), gestational age (OR, 1.68 per week ≥24 weeks; CI, 1.44-1.95; p < 0.001), abnormal FHT (OR, 12.72; CI, 5.19-31.17; p < 0.001), and premature rupture of membranes (OR, 35.97; CI, 7.28-177.74; p < 0.001). CONCLUSION: The FD rate was approximately 10% for PTPs with viable fetal gestational age. Independent risk factors for (+) FD included maternal and fetal factors, many of which are available on initial trauma bay evaluation. These risk factors may help predict FD in the trauma setting and shape future guidelines regarding the recommended observation of PTPs. LEVEL OF EVIDENCE: Therapeutic/Care Management; Level III.

BACKGROUND: Some reports suggest Diagnostic peritoneal aspiration (DPA) or lavage (DPL) may better select which hypotensive blunt trauma patients (BTPs) require operation, compared to ultrasonography. However, whether both moderately hypotensive (systolic blood pressure [SBP] < 90 mmHg) and severely hypotensive (SBP < 70 mmHg) patients benefit from DPA/DPL is unclear. We hypothesized DPA/DPL used within the first hour increases risk of death for severely vs moderately hypotensive BTPs. METHODS: The 2017-2019 Trauma Quality Improvement Program database was queried for BTPs ≥ 18 years old with hypotension upon arrival. We compared moderately and severely hypotensive groups. A multivariable logistic regression analysis was performed controlling for age, comorbidities, emergent operation, blood transfusions, and injury profile. RESULTS: From 134 hypotensive patients undergoing DPA/DPL, 66 (49.3%) had severe hypotension. Patients in both groups underwent an emergent operation (43.9% vs 58.8%, P = .09) in a similar amount of time (median, 42-min vs 54-min, P = .11). Compared to the moderately hypotensive group, severely hypotensive patients had a higher rate and associated risk of death (84.8% vs 50.0%, P < .001) (OR 5.40, CI 2.07-14.11, P < .001). The strongest independent risk factor for death was age ≥ 65 (OR 24.81, CI 4.06-151.62, P < .001). DISCUSSION: Among all BTPs undergoing DPA/DPL within the first hour of arrival, an over 5-fold increased risk of death for patients with severe hypotension was demonstrated. As such, DPA/DPL within this group should be used with caution, particularly for older patients, as they may be better served by immediate surgeries. Future prospective research is needed to confirm these findings and elucidate the ideal DPA/DPL population in the modern era of ultrasonography.

BACKGROUND: Stress on the healthcare system requires careful allocation of resources such as renal replacement therapy (RRT). The COVID-19 pandemic generated difficulty securing access to RRT for trauma patients. We sought to develop a renal replacement after trauma (RAT) scoring tool to help identify trauma patients who may require RRT during their hospitalization. STUDY DESIGN: The 2017 to 2020 TQIP database was divided into a derivation (2017 to 2018 data) and validation (2019 to 2020 data) set. A 3-step methodology was used. Adult trauma patients admitted from the emergency department to the operating room or ICU were included. Patients with chronic kidney disease, transfers from another hospital, and emergency department death were excluded. Multiple logistic regression models were created to determine the risk for RRT in trauma patients. The weighted average and relative impact of each independent predictor was used to derive a RAT score, which was validated using area under receiver operating characteristic curve (AUROC). RESULTS: From 398,873 patients in the derivation and 409,037 patients in the validation set, 11 independent predictors of RRT were included in the RAT score derived with scores ranging from 0 to 11. The AUROC for the derivation set was 0.85. The rate of RRT increased to 1.1%, 3.3%, and 20% at scores of 6, 8, and 10, respectively. The validation set AUROC was 0.83. CONCLUSIONS: RAT is a novel and validated scoring tool to help predict the need for RRT in trauma patients. With future improvements including baseline renal function and other variables, the RAT tool may help prepare for the allocation of RRT machines/staff during times of limited resources.

Background: Many techniques for closure of surgical incisions are available to the surgeon, but there is minimal guidance regarding which technique(s) should be utilized at the conclusion of surgery and under what circumstances. Hypothesis: Management of incisions at the conclusion of surgery lacks consensus and varies among individual surgeons. Methods: The Surgical Infection Society membership was surveyed on the management of incisions at the conclusion of surgery. Several case scenarios were provided to test the influences of operation type, intra-operative contamination, and hemodynamic stability on incision management (e.g., close fascia or skin, use of incision/wound vacuum-assisted closure [VAC] device). Responses by two-thirds of participants were required to achieve consensus. Data analysis by χ2 test and logistic regression, a = 0.05. Response heterogeneity was quantified by the Shannon index (SI). Results: Among 78 respondents, consensus was achieved for elective splenectomy (91% close skin/dry dressing). Open appendectomy and left colectomy/end-colostomy had the greatest heterogeneity (SI, 1.68 and 1.63, respectively). During trauma laparotomy, the majority used damage control for hemodynamic instability (53%-67%) but not for hemodynamically stable patients (0%-1.3%; p < 0.001). Additional consensus was achieved for close skin/dry dressing for hemodynamically stable trauma splenectomy patients (87%) and fascia open/wound VAC for hemodynamically unstable colon resection/anastomosis (67%). Fecal diversion for rectal injury and colon resection/anastomosis (both when hemodynamically stable) had high heterogeneity (SI, 1.56 and 1.48, respectively). In penetrating trauma, sentiment was for more use of wet-to-dry dressings and incision/wound VAC with increased contamination in hemodynamically stable patients. Conclusions: Damage control was favored in hemodynamically unstable trauma patients, with use of wet-to-dry dressings and incision/wound VAC with spillage after penetrating trauma. However, most scenarios did not achieve consensus. High variability of practices regarding incision management at the conclusion of surgery was confirmed. Prospective studies and evidence-based guidance are needed to guide decision making at end-operation.

Background: There is little guidance regarding empiric therapy for superficial surgical site infections (SSIs). Management of incisions with signs of SSI lacks consensus and management is variable among individual surgeons. Methods: The Surgical Infection Society was surveyed regarding management of SSIs. Cases were provided with varying wound descriptions, initial wound class (WC), post-operative day, and presence of a prosthesis. Responses were in multiple-choice format; statistics: χ2; α = 0.05. Results: Seventy-eight members responded. For appearance scenarios, respondents believed that both mild erythema (55%) and clear drainage (64%) could be observed, whereas substantial (>3 cm) erythema or purulence should be treated with complete (22% and 50%) or partial (55% and 40%) opening of the incision. Degree of erythema did not influence administration of antibiotic agents, but purulence was more likely than clear drainage to be treated with antibiotics (38% vs. 6%; p < 0.001). There were no differences based on WC, except that clean cases were more likely than higher WC scenarios to be treated with gram-positive coverage alone (WC 1 [26%] vs. 2 [10%] vs. 3 [13%] vs. 4 [4%]; p < 0.001). Post-operative day (POD) three appeared to be an inflection point for more aggressive treatment of suspected incisional SSI, with fewer (POD 0 [86%] vs. POD day 3 [54%]; p < 0.001) reporting observation. Respondents were more likely to obtain imaging, start broad-spectrum antibiotic agents, and return to the operating room for purulence in the presence of a mesh. Conclusions: Presented with escalating possibility of SSI, respondents reported lower rates of observation, increased use of antibiotic agents, and increased surgical drainage. Many scenarios lack consensus regarding appropriate therapy. The complete elimination of SSIs is unlikely to be accomplished soon, and this study provides a framework for understanding how surgeons approach SSIs, and potential areas for further research or pragmatic guidance.

BACKGROUND: The Trauma and Injury Severity Score (TRISS) uses anatomic/physiologic variables to predict outcomes. The National Surgical Quality Improvement Program Surgical Risk Calculator (NSQIP-SRC) includes functional status and comorbidities. It is unclear which of these tools is superior for high-risk trauma patients (American Society of Anesthesiologists Physical Status (ASA-PS) class IV or V). This study compares risk prediction of TRISS and NSQIP-SRC for mortality, length of stay (LOS), and complications for high-risk operative trauma patients. METHODS: This is a prospective study of high-risk (ASA-PS IV or V) trauma patients (≥18 years-old) undergoing surgery at 4 trauma centers. We compared TRISS vs NSQIP-SRC vs NSQIP-SRC + TRISS for ability to predict mortality, LOS, and complications using linear, logistic, and negative binomial regression. RESULTS: Of 284 patients, 48 (16.9%) died. The median LOS was 16 days and number of complications was 1. TRISS + NSQIP-SRC best predicted mortality (AUROC: .877 vs .723 vs .843, P = .0018) and number of complications (pseudo-R2/median error (ME) 5.26%/1.15 vs 3.39%/1.33 vs 2.07%/1.41, P < .001) compared to NSQIP-SRC or TRISS, but there was no difference between TRISS + NSQIP-SRC and NSQIP-SRC with LOS prediction (P = .43). DISCUSSION: For high-risk operative trauma patients, TRISS + NSQIP-SRC performed better at predicting mortality and number of complications compared to NSQIP-SRC or TRISS alone but similar to NSQIP-SRC alone for LOS. Thus, future risk prediction and comparisons across trauma centers for high-risk operative trauma patients should include a combination of anatomic/physiologic data, comorbidities, and functional status.

BACKGROUND: High-quality CT can exclude hollow viscus injury (HVI) in patients with abdominal seatbelt sign (SBS) but performs poorly at identifying HVI. Delay in diagnosis of HVI has significant consequences necessitating timely identification. STUDY DESIGN: This multicenter, prospective observational study conducted at 9 trauma centers between August 2020 and October 2021 included adult trauma patients with abdominal SBS who underwent abdominal CT before surgery. HVI was determined intraoperatively and physiologic, examination, laboratory, and imaging findings were collected. Least absolute shrinkage and selection operator- and probit regression-selected predictor variables and coefficients were used to assign integer points for the HVI score. Validation was performed by comparing the area under receiver operating curves (AUROC). RESULTS: Analysis included 473 in the development set and 203 in the validation set. The HVI score includes initial systolic blood pressure <110 mmHg, abdominal tenderness, guarding, and select abdominal CT findings. The derivation set has an AUROC of 0.96, and the validation set has an AUROC of 0.91. The HVI score ranges from 0 to 17 with score 0 to 5 having an HVI risk of 0.03% to 5.36%, 6 to 9 having a risk of 10.65% to 44.1%, and 10 to 17 having a risk of 58.59% to 99.72%. CONCLUSIONS: This multicenter study developed and validated a novel HVI score incorporating readily available physiologic, examination, and CT findings to risk stratify patients with an abdominal SBS. The HVI score can be used to guide decisions regarding management of a patient with an abdominal SBS and suspected HVI.

BACKGROUND: The management of complicated ventral hernias (CVH), namely ventral hernias in actively or recently infected/contaminated operative fields, and open abdomens in which the native fascia cannot be primarily reapproximated, pose a surgical challenge. Fetal Bovine and Porcine Acellular Dermal Matrix (BADM and PADM) biologic meshes are being increasingly used in these scenarios. A comparison, however, of clinically relevant outcomes between the two is lacking. With this investigation, we aim to review and compare clinically relevant outcomes in patients that underwent abdominal wall herniorrhaphy with either BADM or PADM at a tertiary urban academic institution over a 5-year period. METHODS: Patients who had a BADM or PADM implanted during CVH over a 5-year period at a tertiary urban academic hospital were identified. Baseline clinical and hernia characteristics, as well as postoperative outcomes were compared after a retrospective chart review. Phone interviews were also conducted to assess for recurrence, followed by in-person visits as indicated. Cox Proportional Hazard regression was fitted to identify risk factors for recurrence. RESULTS: Of the 140 patients who underwent biologic mesh implantation for CVH, 109 were for ventral hernia repair and 31 for open abdomen bridging. Mean age was 52.7 ± 14.2 and males constituted 57.9% of our sample, while 25.1% had undergone > 5 prior abdominal operations. Thirty percent were active smokers, and another 30% required emergency surgery. Only immunosuppression was a risk factor for recurrence [HR 13.3 (1.04-169.2), p = 0.047] on Cox Proportional Hazard regression, while mesh selection had no effect. CONCLUSIONS: Both BADM and PADM meshes perform well in CVH, with satisfactory recurrence rates, only slightly higher compared to traditional synthetic mesh repairs.

Binge eating disorder is characterized by excessive consumption of highly palatable food within short periods of time accompanied by loss of control over eating. Extensive evidence provides support for the consideration of binge eating disorder as an addiction-like disorder. In this study, we wanted to determine whether rats undergoing an operant binge-like eating procedure could develop maladaptive forms of conditioned feeding behaviors. For this purpose, we trained male rats to self-administer either a sugary, highly palatable diet ("Palatable" rats) or a chow diet ("Chow" rats) for 1 hour a day. After escalation and stabilization of palatable food intake, we tested Chow and Palatable rats in (a) a conditioned place preference test, (b) a second-order schedule of reinforcement, (c) a cue-induced suppression of feeding test. In the conditioned place preference task, Palatable rats spent significantly more time in the compartment that was previously paired with the palatable food, compared to Chow controls. Furthermore, in the second-order schedule of reinforcement task, Palatable rats exhibited active lever responding 4- to 6-fold higher than Chow control rats. Finally, in the cue-induced suppression of feeding test, although Chow control subjects reduced responding by 32% in the presence of the conditioned punishment, Palatable rats persevered in responding despite the aversive cue. These results further characterize this animal model of binge-like eating and provide additional evidence for the addictive properties of highly palatable food.

RESUMO A quantidade e a qualidade da água potável ingerida estão diretamente relacionadas com a saúde humana. A garantia de segurança e potabilidade depende do funcionamento adequado de etapas que vão desde o tratamento até a distribuição; e, caso alguma delas apresente falhas, pode haver processo de contaminação. Partindo desse pressuposto, objetivou-se com o presente trabalho verificar a qualidade microbiológica da água fornecida em bebedouros de escolas públicas e privadas de ensino fundamental e infantil da cidade de Santa Rita, na Paraíba. As análises de coliformes totais, termotolerantes e bactérias heterotróficas foram realizadas segundo os padrões e metodologias da American Public Health Association. Por meio dos resultados deste trabalho, baseados nos padrões contidos na Portaria nº 2.914, de 12 de dezembro de 2011, do Ministério da Saúde, em relação à contagem de coliformes totais, verificou-se que 100% das amostras apresentavam-se impróprias para consumo, enquanto coliformes termotolerantes foram detectados em 33,33% das amostras). A contagem de bactérias heterotróficas variou entre 1,5x102 e 1,6x103 UFC.mL-1, sendo assim, todas as amostras foram consideradas impróprias ao consumo humano. Sugere-se um rigoroso controle de qualidade e a adoção de boas práticas, tais como tratamento da água, limpezas periódicas e manutenção dos reservatórios, filtros e bebedouros, bem como medidas preventivas e corretivas para manutenção da higiene e do controle microbiológico dos reservatórios de água, de forma a ser disponibilizada água com qualidade.
ABSTRACT The quantity and the quality of drinking water intake are directly related to human health. In order to guarantee the safety and potability of drinking water, a series of steps ranging from treatment to distribution must work properly, and if any of them fails, contamination can occur. Based on this assumption, the aim of the present work was to check the microbiological water quality in drinking fountains from pre-school and elementary public and private schools in the city of Santa Rita, Paraíba, Brazil. The analyzes of total coliforms, thermotolerant bacteria and heterotrophic bacteria were carried out according to the standards and methodologies of the American Public Health Association. Based on the standards from Decree 2,914 of December 12, 2011, from the Brazilian Health Ministry, of the total coliforms, 12 samples (100%) were unfit for consumption, and thermotolerant coliforms were detected in 33.33% of the samples. The heterotrophic bacteria count ranged from 1.5x102 to 1.6x103 CFU.mL-1, and as such, all of the samples were unsuitable for human consumption. Thus, we suggest the implementation of a rigorous maintenance process that monitors and controls hygiene and microbiological contamination in the drinking fountains at these locations. Additionally, we recommend the adoption of preventive and corrective measures such as water treatment, regular cleaning and the maintenance of reservoirs, filters and drinking fountains, in order to provide quality water at these schools.
