Clinical characteristics, management, and outcomes of severe tetanus in the intensive care unit.
Observational study in BMC infectious diseases, 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
backgroundTetanus is a life-threatening but vaccine-preventable disease. Despite existing preventive measures, severe tetanus continues to impose a significant burden in low- and middle-income countries. However, contemporary data on the clinical characteristics, treatment strategies, complications, and prognosis of patients with severe tetanus remain limited.
methodsWe conducted a retrospective observational cohort study of adult patients with severe tetanus (Ablett grade III or IV) admitted to the intensive care unit (ICU) of a tertiary infectious disease hospital from January 2014 to December 2024. Patient demographics, clinical manifestations, laboratory findings, treatment strategies, complications, and outcomes were extracted from electronic medical records and summarized using descriptive statistical methods.
resultsA total of 36 patients were included, the majority were older men from rural areas, and relatively few had received post-exposure prophylaxis. In the early stage of the disease, dysphagia and generalized muscle hypertonia were more frequent than classic symptoms such as trismus and opisthotonos. Most patients required tracheostomy, deep sedation, neuromuscular blockade, and invasive mechanical ventilation. Infectious complications were common, particularly pulmonary infections (80.6%). More than half of the patients (55.6%) had culture results indicating antimicrobial resistance. The median ICU length of stay was 27.5 days, and the in-hospital mortality rate was 16.7%.
conclusionAlthough severe tetanus is potentially fatal, outcomes can be improved with advanced intensive care management. Early intervention, comprehensive supportive therapy, strict infection control, and strengthened tetanus vaccination and post-exposure prophylaxis strategies are crucial.
