A female has history of 6 weeks amenorrhoea, USG shows no sac, serum beta HCG-1000 IU/L. What would be the next step in management of the patient?
**Core Concept**
The patient is presenting with delayed menstruation and a low serum beta HCG level, which raises suspicion of early pregnancy loss or ectopic pregnancy. However, the absence of a gestational sac on ultrasound (USG) and a low beta HCG level are not definitive indicators of a non-viable pregnancy, and further evaluation is necessary to determine the cause of the patient's symptoms.
**Why the Correct Answer is Right**
Given the patient's symptoms and laboratory results, the next step in management would be to repeat the beta HCG level in 48-72 hours to assess for a rise in hormone levels, which would indicate a viable intrauterine pregnancy. This approach is based on the fact that a viable intrauterine pregnancy typically shows a doubling of beta HCG levels every 48-72 hours. If the beta HCG level has not risen or has fallen, it may indicate a non-viable pregnancy or ectopic pregnancy, which would require further evaluation and possible intervention.
**Why Each Wrong Option is Incorrect**
**Option A:** Immediate surgical intervention is not indicated at this stage, as the patient's symptoms and laboratory results do not definitively indicate a non-viable or ectopic pregnancy.
**Option B:** Repeating the ultrasound in 48 hours may not provide additional information, as the absence of a gestational sac does not rule out a viable intrauterine pregnancy.
**Option C:** Administering methotrexate for a suspected ectopic pregnancy is not appropriate without further evaluation, as the patient's symptoms and laboratory results do not definitively indicate an ectopic pregnancy.
**Option D:** Performing a laparoscopy is an invasive procedure that is not indicated at this stage, as the patient's symptoms and laboratory results do not definitively indicate a non-viable or ectopic pregnancy.
**Clinical Pearl / High-Yield Fact**
In cases of suspected early pregnancy loss or ectopic pregnancy, it is essential to repeat the beta HCG level in 48-72 hours to assess for a rise in hormone levels, which would indicate a viable intrauterine pregnancy. This approach can help avoid unnecessary invasive procedures and improve patient outcomes.
**Correct Answer:** B. Repeating the beta HCG level in 48-72 hours to assess for a rise in hormone levels.
