Tamsett Z, Douglas N, King C, Johnston T, Bentley C, Hao B, Prinsloo D, Bourke EM. Does the choice of induction agent in rapid sequence intubation in the emergency department influence the incidence of post-induction hypotension? Emerg Med Australas 2024; 36:340-347. [PMID: 38018391 DOI: 10.1111/1742-6723.14355] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Revised: 10/26/2023] [Accepted: 11/14/2023] [Indexed: 11/30/2023]
Abstract
OBJECTIVE To describe the effects of different induction agents on the incidence of post-induction hypotension (PIH) and its associated interventions during rapid sequence intubation (RSI) in the ED. METHODS A single centre retrospective study of patients intubated between 2018 and 2021 was conducted in a regional Australian ED. The impact of induction agent choice, in addition to demographic and clinical factors on the incidence of PIH were determined using descriptive statistics and a multivariate analysis presented as adjusted odds ratios (aORs) and their 95% confidence intervals (CIs). RESULTS Ketamine and propofol, used either individually or in conjunction with fentanyl, were significantly associated with PIH (ketamine aOR 4.5, 95% CI 1.35-14.96; propofol aOR 4.88, 95% CI 1.46-16.29). Age >60 years was associated with a greater requirement for vasopressors (aOR 4.46, 95% CI 2.49-7.97) and a higher risk of mortality after RSI (aOR 4.2, 95% CI 1.87-9.40). Patients with a shock index >1.0 were significantly more likely to require vasopressors (aOR 5.13, 95% CI 2.35-11.2) and have a cardiac arrest within 15 min of RSI (aOR 3.56, 95% CI 1.07-11.8). CONCLUSIONS Exposure to both propofol and ketamine is significantly associated with PIH after RSI, alongside age and shock index. PIH is likely multifactorial in nature, and this data supports the sympatholytic effect of induction agents as the underlying cause of PIH rather than the choice of agent itself. Further prospective work including a randomised controlled trial between induction agents is justified to further clarify this important clinical question.

[PMID: 37151026 PMCID: PMC10170262 DOI: 10.1177/08850666231173847] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2022] [Revised: 04/17/2023] [Accepted: 04/19/2023] [Indexed: 05/09/2023]
Abstract
OBJECTIVE To evaluate the association of etomidate with postintubation hypotension, inflammation, and mortality in critically ill patients with COVID-19. DESIGN International, multicenter, retrospective study. PARTICIPANTS Critically ill patients hospitalized specifically for COVID-19 from three major academic institutions in the US and Europe. MAIN OUTCOME AND MEASURES Patients were allocated into the etomidate (ET) group or another induction agent (OA) group. The primary outcome was postintubation hypotension. Secondary outcomes included postintubation inflammatory status, in-hospital mortality, and mortality at 30 days. RESULTS 171 patients with a median age of 68 (IQR 58-73) years were included (ET, n = 98; OA, n = 73). Etomidate was associated with lower postintubation mean arterial pressure [74.33 (64-85) mm Hg versus 81.84 (69.75-94.25) mm Hg, p = 0.005] compared to other agents. No statistically significant differences were generally observed in inflammatory markers between the two groups at 7- and 14-days after admission to the intensive care unit. In-hospital mortality [77 (79%) versus 41 (56%), p = 0.003] and mortality at 30-days [78 (80%) versus 43 (59%), p = 0.006] were higher in the ET group. In multivariate logistic regression analysis, only etomidate (p = 0.009) and postintubation mean arterial pressure (p < 0.001) had a statistically significant effect on mortality, in contrast to stress-dose steroids (p = 0.301), after adjusting for creatinine (p = 0.695), blood urea nitrogen (p = 0.153), age (p = 0.055), oxygen saturation of hemoglobin (SpO2) (p = 0.941), and fraction of inspired oxygen (FiO2) (p = 0.712). CONCLUSIONS Administration of a single-bolus dose of etomidate in critically ill patients with COVID-19 is associated with lower postintubation mean arterial pressure and higher in-hospital and 30-day mortality compared to other induction agents.

Abstract
Hypotension affects approximately 40% of critically ill patients undergoing emergency intubation and is associated with an increased risk of death. The objective of this study was to examine the association between prophylactic vasopressor administration and the incidence of peri-intubation hypotension and other clinical outcomes. DESIGN A secondary analysis of two multicenter randomized clinical trials. The clinical effect of prophylactic vasopressor administration was estimated using a one-to-one propensity-matched cohort of patients with and without prophylactic vasopressors. SETTING Seven emergency departments and 17 ICUs across the United States. PATIENTS One thousand seven hundred ninety-eight critically ill patients who underwent emergency intubation at the study sites between February 1, 2019, and May 24, 2021. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS The primary outcome was peri-intubation hypotension defined as a systolic blood pressure less than 90 mm Hg occurring between induction and 2 minutes after tracheal intubation. A total of 187 patients (10%) received prophylactic vasopressors prior to intubation. Compared with patients who did not receive prophylactic vasopressors, those who did were older, had higher Acute Physiology and Chronic Health Evaluation II scores, were more likely to have a diagnosis of sepsis, had lower pre-induction systolic blood pressures, and were more likely to be on continuous vasopressor infusions prior to intubation. In our propensity-matched cohort, prophylactic vasopressor administration was not associated with reduced risk of peri-intubation hypotension (41% vs 32%; p = 0.08) or change in systolic blood pressure from baseline (-12 vs -11 mm Hg; p = 0.66). CONCLUSIONS The administration of prophylactic vasopressors was not associated with a lower incidence of peri-intubation hypotension in our propensity-matched analysis. To address potential residual confounding, randomized clinical trials should examine the effect of prophylactic vasopressor administration on peri-intubation outcomes.

Abstract
Importance Hypotension is common during tracheal intubation of critically ill adults and increases the risk of cardiac arrest and death. Whether administering an intravenous fluid bolus to critically ill adults undergoing tracheal intubation prevents severe hypotension, cardiac arrest, or death remains uncertain. Objective To determine the effect of fluid bolus administration on the incidence of severe hypotension, cardiac arrest, and death. Design, Setting, and Participants This randomized clinical trial enrolled 1067 critically ill adults undergoing tracheal intubation with sedation and positive pressure ventilation at 11 intensive care units in the US between February 1, 2019, and May 24, 2021. The date of final follow-up was June 21, 2021. Interventions Patients were randomly assigned to receive either a 500-mL intravenous fluid bolus (n = 538) or no fluid bolus (n = 527). Main Outcomes and Measures The primary outcome was cardiovascular collapse (defined as new or increased receipt of vasopressors or a systolic blood pressure <65 mm Hg between induction of anesthesia and 2 minutes after tracheal intubation, or cardiac arrest or death between induction of anesthesia and 1 hour after tracheal intubation). The secondary outcome was the incidence of death prior to day 28, which was censored at hospital discharge. Results Among 1067 patients randomized, 1065 (99.8%) completed the trial and were included in the primary analysis (median age, 62 years [IQR, 51-70 years]; 42.1% were women). Cardiovascular collapse occurred in 113 patients (21.0%) in the fluid bolus group and in 96 patients (18.2%) in the no fluid bolus group (absolute difference, 2.8% [95% CI, -2.2% to 7.7%]; P = .25). New or increased receipt of vasopressors occurred in 20.6% of patients in the fluid bolus group compared with 17.6% of patients in the no fluid bolus group, a systolic blood pressure of less than 65 mm Hg occurred in 3.9% vs 4.2%, respectively, cardiac arrest occurred in 1.7% vs 1.5%, and death occurred in 0.7% vs 0.6%. Death prior to day 28 (censored at hospital discharge) occurred in 218 patients (40.5%) in the fluid bolus group compared with 223 patients (42.3%) in the no fluid bolus group (absolute difference, -1.8% [95% CI, -7.9% to 4.3%]; P = .55). Conclusions and Relevance Among critically ill adults undergoing tracheal intubation, administration of an intravenous fluid bolus compared with no fluid bolus did not significantly decrease the incidence of cardiovascular collapse. Trial Registration ClinicalTrials.gov Identifier: NCT03787732.

Abstract
BACKGROUND Diastolic dysfunction is a risk factor for postoperative major cardiovascular events. During anesthesia, patients with diastolic dysfunction might experience impaired hemodynamic function and worsening of diastolic function, which in turn, might be associated with a higher incidence of postoperative complications.We aimed to investigate whether patients with diastolic dysfunction require higher doses of norepinephrine during general anesthesia. Furthermore, we aimed to examine the association between the grade of diastolic dysfunction and the E/e' ratio during anesthesia. A high E/e' ratio corresponds to elevated filling pressures and is an important measure of impaired diastolic function. METHODS We conducted a prospective observational cohort study at a German university hospital from February 2017 to September 2018. Patients aged ≥60 years and undergoing general anesthesia (ie, propofol and sevoflurane) for elective noncardiac surgery were enrolled. Exclusion: mitral valve disease, atrial fibrillation, and implanted mechanical device.The primary outcome parameter was the administered dose of norepinephrine within 30 minutes after anesthesia induction (μg·kg-1 30 min-1). The secondary outcome parameter was the change of Doppler echocardiographic E/e' from ECHO1 (baseline) to ECHO2 (anesthesia). Linear models and linear mixed models were used for statistical evaluation. RESULTS A total of 247 patients were enrolled, and 200 patients (75 female) were included in the final analysis. Diastolic dysfunction at baseline was not associated with a higher dose of norepinephrine during anesthesia (P = .6953). The grade of diastolic dysfunction at baseline was associated with a decrease of the E/e' ratio during anesthesia (P < .001). CONCLUSIONS We did not find evidence for an association between diastolic dysfunction and impaired hemodynamic function, as expressed by high vasopressor support during anesthesia. Additionally, our findings suggest that diastolic function, as expressed by the E/e' ratio, does not worsen during anesthesia.

Abstract
Rapid identification of Candida species facilitates pathogen-directed therapy with either fluconazole or an echinocandin. METHOD We applied Sepsityper matrix-assisted laser desorption ionisation time of flight mass spectrometry (MALDI-TOF-MS) technology on positive blood culture broths for rapid species identification. RESULTS Of the 74 patients with candidaemia, 25 had the species identified on the day of the positive blood culture directly from the broth (rapid identification group) while the remaining 49 had the species identified from culture (conventional identification group). Three (13.6%) out of 22 treated patients in the rapid identification group received echinocandin compared to 20/45 (44.4%) in the conventional identification group. The appropriateness of therapy was 90.9% in the rapid identification group and 62.2% in the conventional identification group (p = 0.01). Cost savings were more than £10,000 in the first three days of treatment. CONCLUSION Sepsityper-MALDI-TOF-MS is a useful tool in supporting antifungal stewardship programmes.

Background: Peri-intubation cardiac arrest (PICA) following emergent endotracheal intubation (ETI) is a rare, however, potentially preventable type of cardiac arrest. Limited published data have described factors associated with inpatient PICA and patient outcomes. The aim of this study was to identify risk factors associated with PICA among hospitalized patients emergently intubated at a general ward as compared to non-PICA inpatients. In addition, we identified a difference of clinical outcomes in patients between PICA and other types of inpatient cardiac arrest (OTICA). Methods: We conducted a retrospective observational study of patients at two institutions between January 2016 to December 2017. PICA was defined in patients emergently intubated who experienced cardiac arrest within 20 minutes after ETI. The non-PICA group consisted of inpatients emergently intubated without cardiac arrest. Risk factors for PICA were identified through univariate and multivariate logistic regression analysis. Clinical outcomes were compared between PICA and OTICA. Results: Fifteen episodes of PICA occurred during the study period, accounting for 3.6% of all inpatient arrests. Intubation-related shock index, number of intubation attempts, pre-ETI vasopressor use, and neuromuscular blocking agent (NMBA) use, especially succinylcholine, were independently associated with PICA. Clinical outcomes of intensive care unit and hospital length of stay, survival to discharge, and neurologic outcome at hospital discharge were not significantly different between PICA and OTICA. Conclusions: We identified four independent risk factors for PICA, and preintubation hemodynamic stabilization and avoidance of NMBA were possibly correlated with a decreased PICA risk. Clinical outcomes of PICA were similar to those of OTICA.

[PMID: 29315456 DOI: 10.1111/aas.13059] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2017] [Revised: 11/21/2017] [Accepted: 11/29/2017] [Indexed: 01/13/2023]
Abstract
BACKGROUND The benefits of pre-hospital emergency anaesthesia (PHEA) are controversial. Patients who are hypovolaemic prior to induction of anaesthesia are at risk of severe cardiovascular instability post-induction. This study compared mortality for hypovolaemic trauma patients (without major neurological injury) undergoing PHEA with a patient cohort with similar physiology transported to hospital without PHEA. METHODS A retrospective database review was performed to identify patients who were hypotensive on scene [systolic blood pressure (SBP) < 90 mmHg], and GCS 13-15. Patient records were reviewed independently by two pre-hospital clinicians to identify the likelihood of hypovolaemia. Primary outcome measure was mortality defined as death before hospital discharge. RESULTS Two hundred and thirty-six patients were included; 101 patients underwent PHEA. Fifteen PHEA patients died (14.9%) compared with six non-PHEA patients (4.4%), P = 0.01; unadjusted OR for death was 3.73 (1.30-12.21; P = 0.01). This association remained after adjustment for age, injury mechanism, heart rate and hypovolaemia (adjusted odds ratio 3.07 (1.03-9.14) P = 0.04). Fifty-eight PHEA patients (57.4%) were hypovolaemic prior to induction of anaesthesia, 14 died (24%). Of 43 PHEA patients (42.6%) not meeting hypovolaemia criteria, one died (2%); unadjusted OR for mortality was 13.12 (1.84-578.21). After adjustment for age, injury mechanism and initial heart rate, the odds ratio for mortality remained significant at 9.99 (1.69-58.98); P = 0.01. CONCLUSION Our results suggest an association between PHEA and in-hospital mortality in awake hypotensive trauma patients, which is strengthened when hypotension is due to hypovolaemia. If patients are hypovolaemic and awake on scene it might, where possible, be appropriate to delay induction of anaesthesia until hospital arrival.

Predictors of hemodynamic derangement during intubation in the critically ill: A nested case-control study of hemodynamic management-Part II. J Crit Care 2017; 44:179-184. [PMID: 29132057 DOI: 10.1016/j.jcrc.2017.10.018] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2017] [Revised: 09/12/2017] [Accepted: 10/13/2017] [Indexed: 12/20/2022]
Abstract
PURPOSE Our primary aim was to identify predictors of immediate hemodynamic decompensation during the peri-intubation period. METHODS We conducted a nested case-control study of a previously identified cohort of adult patients needing intubation admitted to a medical-surgical ICU during 2013-2014. Hemodynamic derangement was defined as cardiac arrest and/or the development of systolic blood pressure <90mmHg and/or mean arterial pressure <65mmHg 30min following intubation. Data during the peri-intubation period was analyzed. RESULTS The final cohort included 420 patients. Immediate hemodynamic derangement occurred in 170 (40%) patients. On multivariate modeling, age/10year increase (OR 1.20, 95% CI 1.03-1.39, p=0.02), pre-intubation non-invasive ventilation (OR 1.71, 95% CI 1.04-2.80, p=0.03), pre-intubation shock index/1 unit (OR 5.37 95% CI 2.31-12.46, p≤0.01), and pre-intubation modified shock index/1 unit (OR 2.73 95% CI 1.48-5.06, p≤0.01) were significantly associated with hemodynamic derangement. Those experiencing hemodynamic derangement had higher ICU [47 (28%) vs. 33 (13%); p≤0.001] and hospital [69 (41%) vs. 51 (20%); p≤0.001] mortality. CONCLUSIONS Hemodynamic derangement occurred at a rate of 40% and was associated with increased mortality. Increasing age, use of non-invasive ventilation before intubation, and increased pre-intubation shock and modified shock index values were significantly associated with hemodynamic derangement post-intubation.

Abstract
OBJECTIVES Our primary aim was to ascertain the frequency of postintubation hypotension in immunocompromised critically ill adults with secondary aims of arriving at potential risk factors for the development of postintubation hypotension and its impact on patient-related outcomes. METHODS Critically ill adult patients (≥18 years) were included from January 1, 2010, to December 31, 2014. We defined immunocompromised as patients with any solid organ or nonsolid organ malignancy or transplant, whether solid organ or not, requiring current chemotherapy. Postintubation hypotension was defined as a decrease in systolic blood pressure to less than 90 mm Hg or a decrease in mean arterial pressure to less than 65 mm Hg or the initiation of any vasopressor medication. Patients were then stratified based on development of postintubation hypotension. Potential risk factors and intensive care unit (ICU) outcome metrics were electronically captured by a validated data mart system. RESULTS The final cohort included 269 patients. Postintubation hypotension occurred in 141 (52%; 95% confidence interval: 46-58) patients. Several risk factors predicted postintubation hypotension on univariate analysis; however, only Acute Physiology and Chronic Health Evaluation III score in the first 24 hours, preintubation shock status, and preintubation hemodynamic instability remained significant on all 4 multivariate analyses. Patients developing postintubation hypotension had higher ICU and hospital mortality (54 [38%] vs 31 [24%], P = .01; 69 [49%] vs 47 [37%], P = .04). CONCLUSION Based on previous literature, we found a higher frequency of postintubation hypotension in the immunocompromised than in the nonimmunocompromised critically ill adult patients. Acute Physiology and Chronic Health Evaluation III score in the first 24 hours, preintubation shock status, and preintubation hemodynamic instability were significant predictors on multivariate analyses. Postintubation hypotension led to higher ICU and hospital mortality in those experiencing this complication.

Abstract
Tracheal intubation (TI) is a routine procedure in the Intensive Care Unit (ICU) and is often lifesaving. In contrast to the controlled conditions in the operating room, critically ill patients with respiratory failure and shock are physiologically unstable. These factors, along with under evaluation of the airway and suboptimal response to preoxygenation, are responsible for a high incidence of life-threatening complications such as severe hypoxemia and cardiovascular collapse during TI in the ICU. The All India Difficult Airway Association (AIDAA) proposes a stepwise plan for safe management of the airway in critically ill patients. These guidelines have been developed based on available evidence; Wherever, robust evidence was lacking, recommendations were arrived at by consensus opinion of airway experts, incorporating the responses to a questionnaire sent to members of the (AIDAA) and Indian Society of Anaesthesiologists. Noninvasive positive pressure ventilation for preoxygenation provides adequate oxygen stores during TI for patients with respiratory pathology. Nasal insufflation of oxygen at 15 L/min can increase the duration of apnea before hypoxemia sets in. High flow nasal cannula oxygenation at 60-70 L/min may also increase safety during intubation of critically ill patients. Stable hemodynamics and gas exchange must be maintained during rapid sequence induction. It is necessary to implement an intubation protocol during routine airway management in the ICU. Adherence to a plan for difficult airway management incorporating the use of intubation aids and airway rescue devices and strategies is useful.

Abstract
PURPOSE To assess whether exposure to modified shock index (MSI) in the first 24 hours of intensive care unit (ICU) admission is associated with increased in-hospital mortality. METHODS Adult critically ill patients were included in a case-control design with 1:2 matching. Cases (death) and controls (alive) were abstracted by a reviewer blinded to exposure status (MSI). Cases were matched to controls on 3 factors-age, end-stage renal disease, and ICU admission diagnosis. RESULTS Eighty-three cases and 159 controls were included. On univariate analysis, lorazepam administration (odds ratio [OR]: 5.75, confidence interval [CI] = 2.28-14.47; P ≤ .01), shock requiring vasopressors (OR: 3.62, CI = 1.77-7.40; P ≤ .01), maximum MSI (OR: 2.77 per unit, CI = 1.63-4.71; P ≤ .001), and elevated acute physiologic and chronic health evaluation (APACHE) III score at 1 hour (OR: 1.41 per 10 units, CI = 1.19-1.66; P ≤ .001) were associated with mortality. Maximum MSI (OR: 1.93 per unit, CI = 1.07-3.48, P = .03) and APACHE III score at 1 hour (OR: 1.29 per 10 units, CI = 1.09-1.53; P = .003) remained significant with mortality in the multivariate analysis. The optimal cutoff point for high MSI and mortality was 1.8. CONCLUSION Critically ill patients who demonstrate an elevated MSI within the first 24 hours of ICU admission have a significant mortality risk. Given that MSI is easily calculated at the bedside, clinicians may institute interventions earlier which could improve survival.

Abstract
BACKGROUND We aim to report the incidence of post-intubation hypotension in the critically ill, to report in-hospital mortality and length of stay in those who developed post-intubation hypotension, and to explore possible risk factors associated with post-intubation hypotension. MATERIAL/METHODS Adult (≥18 years) ICU patients who received emergent endotracheal intubation were included. We excluded patients if they were hemodynamically unstable 60 minutes pre-intubation. Post-intubation hypotension was defined as the administration of any vasopressor within 60 minutes following intubation. RESULTS Twenty-nine patients developed post-intubation hypotension (29/147, 20%). Post-intubation hypotension was associated with increased in-hospital mortality (11/29, 38% vs. 19/118, 16%) and length of stay (21 [10-37] vs. 12 [7-21] days) on multivariate analysis. Three risk factors for post-intubation hypotension were identified on multivariate analysis: 1) decreasing mean arterial pressure pre-intubation (per 5 mmHg decrease) (p-value=0.04; 95% CI 1.01-1.55); 2) administration of neuromuscular blockers (p-value=0.03; 95% CI 1.12-6.53); and 3) intubation complication (p-value=0.03; 95% CI 1.16-15.57). CONCLUSIONS Post-intubation hypotension was common in the ICU and was associated with increased in-hospital mortality and length of stay. These patients were more likely to have had lower mean arterial pressure prior to intubation, received neuromuscular blockers, or suffered a complication during intubation.
