Esketamine vs. sufentanil for anesthesia induction in elderly patients undergoing transbronchial lung biopsy (TBLB): effect on hemodynamic stability, airway reactivity, and oxygenation.
Article in BMC anesthesiology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundElderly patients undergoing transbronchial lung biopsy (TBLB) face anesthesia-associated complications from cardiopulmonary impairment and comorbidities, so geriatric TBLB anesthetic management is crucial.
aimTo compare esketamine and sufentanil on hemodynamics, airway pressure, bronchospasm incidence and oxygenation in elderly TBLB induction.
methodsUsing a retrospective propensity score matching (PSM) cohort study design, We enrolled recruited elderly patients undergoing TBLB at the Hospital between January 2024 and August 2025. Patients were divided by anesthesia induction protocol: control group (Group S, sufentanil combination) and experimental group (Group E, esketamine combination). A 1:1 PSM method was used to match 40 patients in each group. Primary outcomes included heart rate (HR), mean arterial pressure (mBP), blood oxygen saturation (SpO₂) and airway pressure (Paw) at the time of entering the operating room (T0), LMA insertion (T1), bronchoscopic biopsy (T2), the end of operation (T3), and LMA removal (T4). The incidence of bronchial smooth muscle spasm was observed under the microscope. Secondary outcomes were extubation time, recovery time, and PONV incidence.
resultsAfter PSM, baseline characteristics were comparable (P>0.05). At time points of high stimulation (T1, T2), Group E had significantly higher HR and mBP than Group S (P<0.05). This translated to a markedly lower incidence of clinically significant hypotension requiring intervention in Group E (12.5% vs. 45.0%, P = 0.001). Group E also exhibited significantly lower Paw at T1-T3, higher SpO₂ at T2, and a markedly reduced incidence of bronchospasm (5.0% compared to 22.5%, P<0.05). Recovery profiles favored Group E, showing shorter extubation and recovery times alongside a lower incidence of PONV (P<0.05).
conclusionsIn this retrospective study, esketamine showed associations with improved hemodynamic stability, lower incidence of bronchospasm and airway pressure, reduced PONV, and better oxygenation during induction in elderly TBLB patients, suggesting its potential as a viable alternative.
