OBJECTIVO: Na cirurgia lombar, a instrumentação pedicular proporciona a estabilização dos segmentos afectados e favorece a artrodese. Trata-se na maioria das vezes de procedimentos complexos em pacientes idosos e com várias co-morbilidades. O número de níveis a descomprimir/artrodesar nem sempre é consensual. Os autores pretendem determinar se existe relação entre o número de níveis operados e as complicações intra e pós-operatórias. MÉTODOS: Estudo retrospectivo que incluiu 50 indivíduos com estenose lombar submetidos a descompressão e fixação vertebral posterior entre 2009 e 2010. Idade média 65,98±8,82 anos. Contabilização dos níveis instrumentados (NI) e níveis descomprimidos (ND). Variáveis averiguadas: Tempo de recobro em unidade pós-anestésica/intensivos (UPA); Unidades de glóbulos rubros transfundidos (GR); Variação da concentração de Hemoglobina (Hgb); Tempo cirúrgico (minutos); dias de internamento; ASA score (American Society of Anesthesiologists). Contabilização das complicações neurológicas, infecciosas, vasculares, Mau posicionamento parafusos e doentes reoperados. Divisão em dois grupos: Grupo A: ≤3 NI e GrupoB: >3 NI. Estudo estatístico em SPSS®. RESULTADOS: Relação entre NI e ND com mais GR, mais tempo UPA, maior perda Hgb e maior tempo cirúrgico (p<0,05). Relação entre NI e ND com maior número de complicações (p<0,05). Instrumentações/descompressões >3 níveis associadas a maior necessidade de transfusão (p<0,05), mais tempo na UPA (p<0,05), maior perda hemática (p<0,05), maior tempo cirúrgico (p<0,05) e maior incidência de complicações (p<0,05). CONCLUSÃO: Na estenose lombar, instrumentações/descompressões acima de três níveis têm taxa de complicações mais elevada, assim, no planeamento pré-operatório a relação risco/benefício deve ser ponderada particularmente nos pacientes mais idosos e com mais co-morbilidades.

Abstract BackgroundThe American Society of Anesthesiologists Physical Status Classification (ASA) score is used for communication of patient health status, risk scoring, benchmarking and financial claims. Prior studies using hypothetical scenarios have shown poor concordance of ASA scoring among healthcare providers. However, there is a paucity of concordance studies using real-world data, as well as studies of clinical factors or patient outcomes associated with discordant scoring. The study aims to assess real-world ASA score concordance between surgeons and anesthesiologists, factors surrounding discordance and its impact on patient outcomes. MethodsThis retrospective cohort study was conducted in a tertiary academic medical center on 46284 consecutive patients undergoing elective surgery between January 2017 and December 2019. ASA scores entered by surgeons and anesthesiologists, patient demographics, and post-operative outcomes were collected. We assessed the concordance of preoperative ASA scoring between surgeons and anesthesiologists, clinical factors associated with score discordance, the impact of score discordance on clinically important outcomes, and the discriminative ability of the two scores for 30-day mortality, 1-year mortality, and intensive care unit (ICU) admission. Statistical tests used included Cohen’s weighted 𝜅 score, chi-square test, t-test, unadjusted odds ratios and logistic regression models. ResultsThe ASA score showed moderate concordance (weighted Cohen’s 𝜅 0.53) between surgeons and anesthesiologists. 15098 patients (32.6%) had discordant scores, of which 11985 (79.4%) were scored lower by surgeons. We found significant associations between discordant scores and anesthesiologist-assessed comorbidities, patient age and race. Patients with discordant scores had a higher risk of 30-day mortality (odds ratio 2.00, 95% confidence interval [CI] = 1.52-2.62, p<0.0001), 1-year mortality (odds ratio 1.53, 95% CI = 1.38-1.69, p < 0.0001), and ICU admission >24 hours (odds ratio 1.69, 95% CI = 1.47-1.94, p< 0.0001), and stratified analyses showed a trend towards higher risk when the surgeons’ ASA score was lower. ConclusionsThere is moderate concordance between surgeons and anesthesiologists in assigning the ASA classification. Discordant ASA scores are associated with adverse patient outcomes. Hence, there is a need for improved standardization of ASA scoring and cross-specialty review in ASA-discordant cases.

Abstract OBJECTIVE To determine the incidence of and potential risk factors for postoperative regurgitation and vomiting (PORV), postoperative nausea and vomiting (PONV), and aspiration pneumonia in geriatric dogs using premedication with maropitant and famotidine, intraoperative fentanyl, and postoperative fentanyl as part of an anesthetic protocol. ANIMALS 105 client-owned geriatric dogs that underwent general anesthesia for a major surgical procedure between January 2019 and March 2020. PROCEDURES Medical records were reviewed to collect data on signalment, historical gastrointestinal signs, American Society of Anesthesiologists (ASA) score, indication for surgery, duration of anesthesia and surgery, patient position during surgery, mode of ventilation, and perioperative administration of maropitant, famotidine, anticholinergics, opioids, colloidal support, NSAID, corticosteroids, and appetite stimulants. The incidence of postoperative regurgitation, vomiting, nausea, and aspiration pneumonia was calculated, and variables were each analyzed for their association with these outcomes. RESULTS 2 of 105 (1.9%) dogs regurgitated, 1 of 105 (1.0%) dogs developed aspiration pneumonia, 4 of 105 (3.8%) dogs exhibited nausea, and no dogs vomited. Identified possible risk factors included older age (≥ 13 years old) for postoperative regurgitation, regurgitation for postoperative aspiration pneumonia, and high ASA score (≥ 4) for both regurgitation and aspiration pneumonia. CONCLUSIONS AND CLINICAL RELEVANCE The use of an antiemetic protocol including maropitant, famotidine, and fentanyl in geriatric dogs resulted in very low incidences of PORV, PONV, and aspiration pneumonia. Future prospective studies are warranted to further evaluate and mitigate postoperative risks.

Összefoglaló. Bevezetés: Az akut varixeredetű gastrointestinalis vérzés napjainkban is jelentős morbiditással és mortalitással jár. Célkitűzés: Célunk az akut varixeredetű felső gastrointestinalis vérzések incidenciájának, ellátási folyamatainak és kimeneteli tényezőinek átfogó felmérése volt. Módszer: Prospektív, multicentrikus vizsgálatunk keretében hat nyugat-magyarországi gasztroenterológiai centrum bevonásával elemeztük az ott diagnosztizált és kezelt, varixvérző betegek adatait. Rögzítettük a demográfiai, az anamnesztikus, a diagnosztikus, valamint a terápiát és a betegség kimenetelét érintő adatokat. Minden beteg esetében kockázat- és predikcióbecslést végeztünk a Glasgow–Blatchford Score (GBS), a pre- és posztendoszkópos Rockall Score (RS) és az American Society of Anesthesiologists (ASA) Score alapján. Eredmények: A vizsgált egyéves periódusban (2016. 01. 01. és 2016. 12. 31. között) 108, akut varixeredetű gastrointestinalis vérzést találtunk (átlagéletkor: 59,6 év). Endoszkópos terápiára 57,4%-ban került sor, 39,8% sclerotherapiában, 18,5% ligatióban részesült. Transzfúziót a betegek 76,9%-a igényelt. A teljes halálozás 24,1% volt. A transzfúziós igény vonatkozásában a legmagasabb prediktív értékű a GBS volt (AUC: 0,793; cut-off: GBS >8 pont). Az ASA-pontszám szignifikáns összefüggést mutatott a transzfúzió-szükséglettel (OR 7,6 [CI 95% 2,7–21,6]; p<0,001), az endoszkópos intervencióval (OR 12,6 [CI 95% 3,4–46,5]; p = 0,033) és trendszerű kapcsolatot a mortalitással (OR 3,6 [0,8–16,7]; p = 0,095). Emellett a nemzetközi normalizált ráta (INR) értéke (p = 0,001) és a szérumkreatinin-szint (p = 0,002) állt kapcsolatban a mortalitással. Az endoszkópos intervenció aránya szignifikáns összefüggésben volt a varix Paquet-stádiumával (p<0,001) és az ASA-pontszámmal (OR = 12,6 [3,4–46,5]; p = 0,033). Következtetés: Nyugat-Magyarországon magas az akut varixeredetű vérzés előfordulási gyakorisága. Az ASA-pontszám és a GBS jó prediktív faktor a betegségkimenetel és a transzfúziós igény vonatkozásában. A megfigyelt magas mortalitás és az endoszkópos ligatio alacsony aránya indokolja a kezelési stratégiák optimalizálását akut varixeredetű gastrointestinalis vérzés esetén. Orv Hetil. 2021; 162(31): 1252–1259. Summary. Introduction: Acute variceal gastrointestinal bleeding is associated with significant morbidity and mortality. Objective: Our aim was to evaluate the characteristics and prognostic factors in the management of acute upper gastrointestinal bleeding in a large multi-center study from Hungary. Method: This prospective one-year study (between January 1, 2016 and December 31, 2016) involved six community hospitals in Western Hungary. Data collection included demographic characteristics, vital signs at admission, comorbidities, medications, time to hospital admission and endoscopy, laboratory results, endoscopic management, risk assessment using Glasgow–Blatchford Score (GBS), Rockall Score (RS) and the American Society of Anesthesiologists (ASA) Physical Status Score, transfusion requirements, length of hospital stay and mortality. Results: 108 cases (male: 69.4%) of acute variceal gastrointestinal bleeding were registered during the 1-year period. Endoscopic therapeutic intervention was performed in 57.4%. On initial endoscopy, 39.8% of the patients were treated with sclerotherapy and 18.5% had ligation. 76.9% of the patients required blood transfusion. The overall mortality (including in-hospital bleedings) was 24.1%. The GBS predicted transfusions (AUC: 0.793; cut-off: GBS >8 points). The ASA Score was associated with transfusion (OR 7.6 [CI 95% 2.7–21.6]; p<0.001), endoscopic intervention (OR 12.6 [CI 95% 3.4–46.5]; p = 0.033), and showed similar trend with mortality (OR 3.6 [0.8–16.7]; p = 0.095). The increased international normalized ratio (INR) and creatinine levels were associated with mortality (p = 0.001 and p = 0.002). Conclusion: Incidence rates of acute variceal gastrointestinal bleeding in Western Hungary are high. The ASA Score, GBS predicted outcomes and transfusion requirements. The observed high mortality rates, coupled with relatively low rates of endoscopic ligation, warrant optimization of management strategies in acute variceal gastrointestinal bleeding.

IntroductionAs a research team of urologists and an anesthetist, we sought to investigate the prognostic significance of American Society of Anesthesiologists (ASA) score in patients with upper tract urothelial cancer (UTUC) after radical nephroureterectomy (RNU). ASA physical status (ASA-PS) classification not only was found to be associated with increased comorbidities but also independently factors for predicting morbidity and mortality. Accurate risk assessment was being particularly important for patients being considered for surgery.MethodsRecords for 958 patients with UTUC who underwent RNU were reviewed. Clinicopathologic variables, including ASA-PS, were assessed at two institutions. Overall survival (OS), cancer-specific survival (CSS), intravesical recurrence-free survival (IRFS), and metastasis-free survival (MFS) were estimated using the Kaplan–Meier method and Cox regression analyses. We measured the independent predictive value of ASA-PS for mortality by multivariate regression. Association of ASA-PS and clinicopathologic variables was assessed.ResultsThe group of patients with ASA = 2/3 had a shorter 5-year OS (67.6% and 49.9%), CSS (72.9% and 58.1%), and MFS (75.1% and 58.5%). The median follow-up time was 39 months. Kaplan–Meier curves showed that the group with ASA = 2/3 had significantly poorer OS, CSS, and MFS. Adjusting for multiple potential confounding factors, multivariate analyses suggested that ASA score was an independent predictor of OS, CSS, and MFS (p = 0.004, p = 0.005, p &lt; 0.001).ConclusionHigher ASA scores were independently associated with lower survival rate. This capability, along with its simplicity, makes it a valuable prognostic metric. It should be seriously referenced in UTUC patients being considered for RNU.

AbstractBackgroundThe American Society of Anesthesiologists (ASA) Physical Status Classification System defines peri-operative patient scores as 1 (healthy) thru 6 (brain dead). The scoring is used by the anesthesiologists to classify surgical patients based on co-morbidities and various clinical characteristics. The classification is always done by an anesthesiologist prior operation. There is a variability in scoring stemming from individual experiences / biases of the scoring anesthesiologists, which impacts prediction of operating times, length of stay in the hospital, necessity of blood transfusion, etc. In addition, the score affects anesthesia coding and billing. It is critical to remove subjectivity from the process to achieve reproducible generalizable scoring.MethodsA machine learning (ML) approach was used to associate assigned ASA scores with peri-operative patients’ clinical characteristics. More than ten ML algorithms were simultaneously trained, validated, and tested with retrospective records. The most accurate algorithm was chosen for a subsequent test on an independent dataset. DataRobot platform was used to run and select the ML algorithms. Manual scoring was also performed by one anesthesiologist. Intra-class correlation coefficient (ICC) was calculated to assess the consistency of scoringResultsRecords of 19,095 procedures corresponding to 12,064 patients with assigned ASA scores by 17 City of Hope anesthesiologists were used to train a number of ML algorithms (DataRobot platform). The most accurate algorithm was tested with independent records of 2325 procedures corresponding to 1999 patients. In addition, 86 patients from the same dataset were scored manually. The following ICC values were computed: COH anesthesiologists vs. ML – 0.427 (fair); manual vs. ML – 0.523 (fair-to-good); manual vs. COH anesthesiologists – 0.334 (poor).ConclusionsWe have shown the feasibility of using ML for assessing the ASA score. In principle, a group of experts (i.e. physicians, institutions, etc.) can train the ML algorithm such that individual experiences and biases would cancel each leaving the objective ASA score intact. As more data are being collected, a valid foundation for refinement to the ML will emerge.

AbstractTotal knee arthroplasty (TKA) in patients with peripheral vascular disease has sparsely been studied. This study examined patient and radiographic factors that could affect reoperation free survival in these patients. We retrospectively reviewed TKA procedures performed in patients with nonpalpable pulses on physical examination between January 1, 2004, and December 31, 2013. Ninety-two cases met inclusion criteria. Preoperative ankle-brachial index (ABI), date of surgery, sex, age, body mass index (BMI), tourniquet use, American Society of Anesthesiologists (ASA) score, presence of preoperative calcifications, and follow-up data were obtained. Failure was defined as reoperation. Patients were included if they experienced a failure or had at least 2 years of follow-up. Reoperation free survival was calculated by Kaplan–Meier's analysis. Odds ratios (ORs) were calculated for patient factors; hazard ratios (HRs) were calculated by Cox's regression analysis. Ninety-two TKAs were included in the study. Mean age was 68.8 years, mean BMI was 32.15, and mean ASA score was 2.44. Tourniquet was used in 78 patients. Mean preoperative ABI was 1.016. Nine patients had calcifications on X-ray prior to surgery. Reoperation free survival was 9.378 years. Patients with a preoperative ABI of below 0.7 had shorter reoperation free survival (ABI <0.7, 6.854 years; ABI >0.7, 9.535 years; p = 0.015). Patients with a preoperative ABI below 0.7 had greater odds of failure and were at higher risk for earlier failure (OR = 6.5, p = 0.027; HR = 1.678, p = 0.045). When corrected for age, sex, and BMI, the HR for patients with a preoperative ABI below 0.7 worsened (HR = 1.913, p = 0.035) compared with those with an ABI above 0.7. The remaining patient factors produced no statistically significant differences in survivorship, odds of failure, or HRs. No patient factors were associated with increased risk of mortality. These results suggest that patients who undergo TKA with an ABI below 0.7 are at increased risk for reoperation and have shorter reoperation free survival.

Introduction Robotic colectomy could reduce morbidity and postoperative recovery over laparoscopic and open procedures. This comparative review evaluates colectomy outcomes based on surgical approach at a single community institution. Methods A retrospective review of all patients who underwent colectomy by a fellowship-trained colon and rectal surgeon at a single institution from 2015 through 2019 was performed, and a cohort developed for each approach (open, laparoscopic, and robotic). 30-day outcomes were evaluated. For dichotomous outcomes, univariate logistic regression models were used to quantify the individual effect of each predictor of interest on the odds of each outcome. Continuous outcomes received a similar approach; however, linear and Poisson regression modeling were used, as appropriate. Results 115 patients were evaluated: 14% (n = 16) open, 44% (n = 51) laparoscopic, and 42% (n = 48) robotic. Among the cohorts, there was no statistically significant difference in operative time, rate of reoperation, readmission, or major complications. Robotic colectomies resulted in the shortest length of stay (LOS) (Kruskal-Wallis P < .0001) and decreased estimated blood loss (EBL) (Kruskal-Wallis P = .0012). Median age was 63 years (interquartile range [IQR] 53-72). 54% (n = 62) were female. Median American Society of Anesthesiologists physical status classification was 3 (IQR 2-3). Median body mass index was 28.67 (IQR 25.03-33.47). A malignant diagnosis was noted on final pathology in 44% (n = 51). Conclusion Among the 3 approaches, there was no statistically significant difference in 30-day morbidity or mortality. There was a statistically significant decreased LOS and EBL for robotic colectomies.

Background: Decreased length of stay after total joint arthroplasty (TJA) is becoming a more common way to contain healthcare costs and increase patient satisfaction. There is little evidence to support “early” discharge in elderly patients. Purpose: We sought to identify preoperative factors that correlated with early discharge (by postoperative day [POD] 1) in comparison to late discharge (after POD2) in octogenarians after TJA. Methods: In a retrospective cohort study from a single institution, we identified 482 patients ages 80 to 89 who underwent primary TJA from January 2014 to December 2017; 319 had total knee arthroplasty (TKA) and 163 had total hip arthroplasty (THA). Data collected included preoperative knee range of motion (ROM), demographics, and comorbidities; 90-day readmission and mortality rates were also evaluated. P values for continuous data were calculated using student’s t test and for categorical data using χ2 testing. Results: Of octogenarian patients, 30.9% were discharged by POD1. Early discharge was associated with being male, married, and nonsmoking, as well as having an American Society of Anesthesiologists (ASA) score of 2, independent preoperative ambulation, and a postoperative caregiver. Type of procedure (TKA vs THA), body mass index, laterality, preoperative range of motion (ROM) for TKA, and single vs multilevel home did not affect the probability of early discharge. Discharge on POD1 was not associated with increased 90-day readmission rates. There were no deaths. Conclusion: Early discharge for octogenarians can be successfully implemented in a select subset of patients without increasing 90-day readmission or death rates. There are multiple factors that predict successful early discharge.
