Sepsis is a life-threatening medical emergency in which the body’s response to infection causes organ dysfunction. It can develop from pneumonia, urinary tract infections, abdominal infections, skin infections and other sources. Without timely recognition and treatment, patients may deteriorate rapidly and require intensive care.
For doctors working in Indian hospitals, sepsis recognition and managementrequires a structured approach to bedside assessment, initial resuscitation, antimicrobial treatment and escalation. Increasing antimicrobial resistance adds another challenge because some infections are becoming harder to treat with standard antibiotics.
This guide explains practical steps for early sepsis recognition, the first-hour bundle, fluid management and referral to critical care. It is intended for adult ward practice and should be applied alongside local hospital protocols and senior clinical judgement.
Sepsis is life-threatening organ dysfunction caused by a dysregulated response to infection. It is not simply another term for fever, a positive blood culture or a severe localised infection.
Possible signs of infection include fever, chills, cough, painful urination, abdominal pain or an infected wound. Signs suggesting organ dysfunction may include altered mental status, low blood pressure, reduced urine output, rapid breathing, hypoxaemia or worsening kidney function.
Septic shock is a more severe form of sepsis involving circulatory and cellular or metabolic abnormalities. Clinically, persistent hypotension despite adequate fluid resuscitation may indicate the need for vasopressors and urgent critical care.
Doctors should remember that sepsis can occur without fever. Older adults, immunocompromised patients and people with significant comorbidities may present with confusion, weakness, reduced urine output or unexplained deterioration rather than typical infection symptoms.
Early sepsis recognition begins with clinical suspicion, complete observations and repeated reassessment. No single score or laboratory test can independently confirm or exclude sepsis.
The National Early Warning Score 2 (NEWS2) combines respiratory rate, oxygen saturation, supplemental oxygen use, temperature, systolic blood pressure, pulse and consciousness level. It helps identify acute deterioration and supports decisions about clinical review.
In adult acute hospital settings, NICE recommends NEWS2 for assessing the risk of severe illness or death in people with suspected sepsis. A score of 5–6 indicates moderate risk, while a score of 7 or above indicates high risk under this framework. Clinical concerns may justify escalation even when the total score is lower.
The quick Sequential Organ Failure Assessment (qSOFA) includes three findings:
A score of 2 or more identifies patients with suspected infection who may be at increased risk of poor outcomes. However, qSOFA is not a reliable standalone screening tool and can miss patients with sepsis. The Surviving Sepsis Campaign recommends NEWS, NEWS2, MEWS or SIRS over qSOFA alone for hospital screening.
Escalate promptly when a patient has severe hypotension, rapidly increasing oxygen requirements, new confusion, mottled or cyanotic skin, markedly reduced urine output or signs of poor peripheral perfusion.
Do not wait for a score to reach a threshold when the patient is deteriorating. Consider alternative or additional diagnoses, including haemorrhage, pulmonary embolism, cardiogenic shock and severe metabolic disturbances.
The first hour is a useful operational target for rapid assessment and treatment. It is not a reason to delay interventions until the hour is complete, and not every intervention is appropriate for every patient.
Assess airway, breathing and circulation. Check vital signs, oxygen saturation, mental status, capillary refill and urine output where relevant. Call for senior help early if the patient is unstable.
Provide oxygen when indicated by hypoxaemia or respiratory compromise, guided by the patient’s clinical condition and appropriate oxygen targets. Establish intravenous access and initiate continuous or frequent monitoring according to severity.
Measure blood lactate when sepsis or septic shock is suspected, and testing is available. An elevated lactate may indicate impaired tissue perfusion, but it can also have other causes. A normal result does not exclude sepsis.
Repeat lactate when initially elevated or when ongoing hypoperfusion is suspected, while interpreting the trend alongside the patient’s clinical response.
Investigations commonly include a complete blood count, renal function, electrolytes, liver function and other tests guided by the suspected source and severity.
Obtain blood cultures and appropriate specimens from the suspected infection site before antibiotics when feasible. Cultures can help identify the pathogen and guide later treatment.
However, sampling must not cause a substantial delay in urgent antimicrobial therapy for a patient with likely sepsis or septic shock.
For septic shock or a high likelihood of sepsis, initiate appropriate empirical antimicrobial therapy immediately, following local protocols and relevant guidelines. Choice should account for the suspected source, likely organisms, local resistance patterns, previous cultures, allergies, renal function and recent antibiotic exposure.
In patients with possible sepsis but no shock, a rapid, time-limited assessment may help determine whether infection is the likely cause before antibiotics are started. The decision should reflect clinical risk and should not become a reason for prolonged delay.
India’s ICMR antimicrobial guidance provides a useful reference for rational antibiotic selection and local stewardship practices.
Intravenous crystalloids are the usual first-line fluids for sepsis-related hypoperfusion. International guidance suggests at least 30 mL/kg within the first three hours for adults with sepsis-induced hypoperfusion or septic shock, but this is not a universal fixed prescription for every patient with suspected sepsis.
Give fluids according to the patient’s haemodynamic status and reassess frequently. Review blood pressure, capillary refill, mental status, urine output, respiratory findings and response to each fluid intervention. Where available, dynamic assessments such as passive leg raising or bedside echocardiography can help evaluate fluid responsiveness.
Patients with heart failure, kidney impairment or signs of fluid overload need particular caution. Persistent hypotension despite appropriate initial resuscitation requires urgent senior and critical care review rather than repeated fluid administration without reassessment.
If hypotension persists despite appropriate fluid resuscitation, vasopressor support may be necessary. Norepinephrine is generally the first-line vasopressor for septic shock, with an initial mean arterial pressure target of approximately 65 mmHg for many adults. Treatment requires close monitoring and appropriate clinical expertise.
Antibiotics alone may not be sufficient when an infection requires drainage, removal of an infected device, surgery or another source-control procedure.
Consider whether an abscess, obstructed urinary system, infected catheter or intra-abdominal infection requires urgent intervention. Early coordination with the relevant surgical or specialist team can be crucial.
Ward doctors should request urgent senior review when the patient has suspected sepsis with organ dysfunction, persistent hypotension, worsening lactate, increasing oxygen needs, reduced urine output or deteriorating consciousness.
Contact the critical care team early when the patient requires vasopressors, advanced respiratory support or close monitoring that cannot safely be delivered on the ward. If the patient fails to respond to initial interventions, reassess the diagnosis, treatment and need for higher-level care.
Document the time of recognition, observations, investigations, antibiotics, fluids, clinical response and escalation decisions. Continue reassessing the patient rather than relying on the initial score or treatment plan.
Suspect sepsis when infection is accompanied by new organ dysfunction, such as altered mental status, hypotension, rapid breathing, reduced urine output or worsening oxygenation. Use NEWS2 where appropriate, but prioritise clinical judgement and reassessment.
Rapid assessment, lactate measurement, appropriate cultures, timely antibiotics, and indicated intravenous fluids and vasopressors when required are key elements. The sequence should be adapted to the patient’s condition without delaying urgent treatment.
Guidelines suggest at least 30 mL/kg of intravenous crystalloid within the first three hours for adults with sepsis-induced hypoperfusion or septic shock. Individualise treatment and repeatedly reassess for benefit and fluid overload.
Escalate immediately for haemodynamic instability, altered consciousness, worsening respiratory status or other evidence of organ dysfunction. Seek critical care support when the patient needs vasopressors, advanced respiratory support or monitoring beyond ward capabilities.
No. qSOFA can identify concerning features but may miss patients with sepsis. Use an appropriate early warning system, clinical assessment and repeated observations.
Sepsis recognition and management in India requires prompt clinical assessment, timely treatment and clear escalation pathways. NEWS2 can support risk assessment, while qSOFA should not be used alone to screen patients. The first-hour approach should prioritise urgent care, appropriate antibiotics, individualised fluid resuscitation and source control.
