Brief Summary

The incidence of thrombocytopenia in ICU patients with severe illness ranged from 8.3% to 67.6%, and ranged from 14% to 44% during ICU treatment.Severe patients with thrombocytopenia also have significantly increased bleeding events and blood transfusions, and even a significantly increased risk of death.This study examines whether elevated platelets benefit patients with pneumonia

Outcome Measures

Primary Outcomes (1)

  • The time to recovery to a normal platelet level

    The clinical recovery time of platelets was defined as the time it takes to reach clinical recovery.

    14 days

Study Arms (2)

the TPO group

EXPERIMENTAL

Patients in TPO group will be treated with rhTPO at a dose of 15000u/d, subcutaneous injection, for 7 consecutive days.

Drug: recombinant human thrombopoietin

the control group

PLACEBO COMPARATOR

Patients in the control group will receive the same amount of saline as a placebo, which is injected subcutaneously, for 7 consecutive days.

Drug: normal saline

Interventions

The dose of rhTPO is 15,000 U per day. The subcutaneous injection will be terminated when PCs are increased to normal. The duration of rhTPO will be 7 days.

the TPO group

Patients in the control group will receive the same amount of saline as a placebo, which is injected subcutaneously. The duration of saline will be 7 days.
