Resuscitate significant haemorrhage while identifying its cause; pregnancy, timing in relation to birth, and the condition of the uterus determine the definitive treatment. A vaginal loss need not originate in the uterus, and the visible volume may underestimate concealed bleeding. Assess consciousness, pulse, blood pressure and ongoing loss; serious bleeding calls for urgent obstetric or gynaecological help, intravenous access, blood sampling and access to blood transfusion. Investigations must not delay control of a life-threatening source.

Outside pregnancy, distinguish excessive menstrual bleeding from irregular, postcoital or postmenopausal bleeding. Causes include uterine fibroids, endometrial polyps, disturbed ovulation, coagulopathy and cancer. A speculum examination may reveal a cervical or vaginal source. History, examination, blood count, and appropriately selected ultrasonography, hysteroscopy or tissue sampling establish the cause. Current treatment for heavy menstrual bleeding may use tranexamic acid or hormonal treatment where suitable; removal of a polyp or treatment of a uterine fibroid addresses a structural cause. Suspected cancer needs a diagnostic and specialist pathway, rather than repeated empirical suppression of bleeding.^[ref]

In early pregnancy, consider threatened or established miscarriage and retained pregnancy tissue. Establish the location and viability of the pregnancy with ultrasonography and, where appropriate, serial human chorionic gonadotropin measurements. Stable cases permit a choice among expectant, medical or surgical management according to the diagnosis and circumstances; heavy ongoing bleeding or instability changes the urgency. An ectopic pregnancy may cause vaginal bleeding together with dangerous internal haemorrhage, even though the bleeding pregnancy is outside the uterus. Pain, collapse or instability therefore demands urgent assessment rather than an assumption that all bleeding represents a harmless menstrual or uterine event.^[ref]

Later pregnancy requires distinction between placenta praevia, placental abruption and other genital-tract sources. Placenta praevia may cause heavy painless bleeding; placental abruption may involve pain, a tense uterus and concealed loss. Stabilise the mother, assess the fetus and locate the placenta by ultrasonography. Avoid a digital examination that could disturb a covering placenta before placenta praevia has been excluded. The timing and route of birth depend on severity, placental position, gestation and maternal and fetal condition. A placenta covering the cervical opening usually requires Caesarean section; the diagnosis is not an instruction to apply a vaginal plug and wait through major continuing loss.^[ref][ref]

During and after birth, organise postpartum haemorrhage causes as poor uterine contraction, retained tissue, genital-tract trauma and defective clotting. A uterine rupture is a surgical emergency; a contracting uterus does not exclude a traumatic source. For uterine atony, uterine massage and a suitable uterotonic accompany resuscitation; emptying a distended urinary bladder may help contraction. Examine for tears and repair them; deal with retained placental tissue with skilled obstetric care, and do not forcibly detach an abnormally adherent placenta. Correct relevant coagulopathy and use blood products as indicated. Current early treatment includes tranexamic acid within the recommended interval. Continuing bleeding may require balloon tamponade or surgery; a uterine inversion requires urgent skilled replacement and resuscitation, not treatment as simple atony. Delayed bleeding after birth suggests retained tissue or infection and requires renewed assessment.^[ref]

An 1864 practitioner could recognise miscarriage, abnormal placental attachment or separation, retained placenta, atony and traumatic bleeding, and could attempt pressure, manual measures and delivery appropriate to the cause. Cold applications and vaginal plugging appeared in period practice, but were not interchangeable cures. Contemporary obstetric discussion already distinguished several mechanisms of bleeding.^[ref] In particular, a uterotonic cannot repair a tear, and obstructing the outflow does not establish that internal haemorrhage has ceased. The modern diagnostic and resuscitative measures above explain why treatment must follow the mechanism rather than the symptom alone.

Treat new convulsions during labour as possible eclampsia: protect breathing, terminate and prevent seizures, control severe hypertension, and plan birth after stabilisation. Previous good health does not exclude pre-eclampsia or eclampsia. Also consider epilepsy, hypoglycaemia, intracranial disease and other causes if the clinical findings suggest them; neither an invented history nor a fabricated urine result is needed to recognise the emergency.

Summon obstetric, anaesthetic and neonatal assistance. Protect the woman from injury, position her safely on her side when feasible, maintain the airway, and assess breathing and oxygen saturation. Do not force an object into her mouth or attempt to suppress a fit by forcefully holding down her limbs. Obtain intravenous access, check blood glucose, and measure blood pressure; assess platelets, renal function, liver tests and proteinuria without delaying essential treatment. Review the fetal condition once maternal resuscitation is under way.

Current first-line anticonvulsant treatment is magnesium sulfate. NICE describes an intravenous loading dose of 4 g over 5–15 minutes, followed by 1 g per hour, with continued treatment for 24 hours after the last fit. Recurrent fits require additional treatment under the emergency protocol. Monitor breathing, tendon reflexes and urine output because impaired renal function increases the risk of magnesium accumulation. A benzodiazepine is not an interchangeable routine substitute for magnesium sulfate in this setting. Severe hypertension requires prompt suitable treatment, for example labetalol, nifedipine or hydralazine, with continuing reassessment.^[ref]

Once stabilised, the woman needs a plan for birth. Cervical findings, progress of labour, gestation and maternal and fetal condition determine whether vaginal birth or Caesarean section is appropriate. Performing an immediate instrumental delivery during an uncontrolled fit is not a general rule, nor does the occurrence of one fit automatically establish the route of birth. Observation and treatment continue after delivery because further fits in eclampsia can occur.^[ref]

Historically, bloodletting, purgation, chloroform and expedited delivery were advocated in different combinations. An actual 1864 case report records such treatment and continuing convulsions despite delivery. It illustrates the historical problem, not proof that removal of blood or pressure on pelvic nerves explains or cures eclampsia.^[ref] Modern eclampsia care replaces those obsolete theories with specific seizure treatment, blood-pressure control and maternal resuscitation.

Severe haemoptysis in a person described historically as “phthisical” requires immediate attention to breathing and circulatory danger; the treatment of chronic wasting cannot wait in place of control of the acute bleeding. The historical label suggests pulmonary tuberculosis, but does not itself prove that diagnosis or identify the bleeding vessel.

In period terms, the sensible supportive aims were quiet, reduced exertion and observation of the blood loss and general condition. The intent was to avoid provoking further cough or dislodging a clot, while preserving the person's remaining strength. A depleted person with chronic wasting was a poor candidate for reflex general bloodletting. The historical pharmacological literature included astringents, mineral salts and external cold, but the mere sequence “remedy administered, bleeding stopped” could not establish efficacy: haemoptysis often varied or stopped temporarily on its own.

This uncertainty was recognized before the examination. An 1862 discussion lists astringents such as lead acetate, emetic drugs and external ice among competing treatments, and questions the evidential value of events following their use. It also records opposing fashions of severe dietary restriction and frequent feeding with stimulants.^[ref] The same author advocated a digitalis preparation with close pulse observation for severe attacks, hoping to influence the circulation; he emphasized its dangers. This is a period proposal, not modern emergency treatment. The historical explanation is why rest and supposed haemostatic remedies were attempted, not a claim that they reliably closed a ruptured vessel. No toxic nineteenth-century mixture is recommended here.

Modern correction: life-threatening haemoptysis is an airway emergency, often killing through obstruction and loss of gas exchange. Its severity depends on respiratory and circulatory effects, not just the estimated volume in a basin. Obtain emergency specialist support, maintain oxygenation and protect the unaffected lung; when the bleeding side is known, positioning that side down can limit contamination of the other side. Secure suitable intravenous access, assess haemoglobin and coagulation, prepare for needed blood transfusion and correct important coagulopathy. In unstable ongoing bleeding, securing the airway and bronchoscopy can take precedence over transport for imaging.^[ref]

Once sufficiently stable, computed tomography angiography helps locate the source and plan treatment. Bronchial artery embolisation is a principal means of controlling severe or recurrent haemoptysis from abnormal systemic vessels. Bronchoscopy can assist localization and temporary control; selected lesions or failed endovascular control may require surgery. Do not assume every tuberculosis-associated haemorrhage comes from the same vascular bed. The intervention must match the demonstrated source. Modern management also treats the underlying disease; stopping bleeding alone does not cure pulmonary tuberculosis.^[ref] Suspected active pulmonary tuberculosis warrants appropriate respiratory infection-control measures, diagnostic sampling when safe and a susceptibility-informed multidrug antibiotic regimen once the diagnosis and treatment plan are established.^[ref] Quiet surroundings can still help, but neither ice nor a historical astringent substitutes for these measures.
