Resistance to Propofol Induction in a Patient Taking Modafinil: A Case Report

Unusual Resistance to Intravenous Anesthetic Drugs in a Rachipagus Infant: A Case Report

In conjoined twins when one of the twins is incompletely formed and is dependent on the healthy counterpart for survival, they are described as heteropagus (parasitic) twins. Rachipagus is a type of parasitic twin joined at the spine above the sacrum. Such neonates can present with complex problems related to anesthesia. We encountered one such infant for a routine contrast-enhanced computed tomography (CECT) angiography under sedation. The infant was resistant to multiple anesthetic drugs like fentanyl, propofol, and ketamine. Later general anesthesia was induced with thiopentone sodium, and the procedure went on uneventfully.

Uncontrolled high blood pressure under total intravenous anesthesia with propofol and remifentanil: A case report

BACKGROUND

Although propofol generally reduces blood pressure, rarely, it causes hypertension. However, the mechanism by which propofol increases blood pressure has not been established, and so far, there are only a few reported cases.

CASE SUMMARY

A 46-year-old woman, diagnosed with thyroid cancer, was administered general anesthesia with propofol and remifentanil for a thyroid lobectomy. An increase in the concentrations of intravenous anesthetics further increased her blood pressure. The blood pressure remained stable when anesthesia was maintained with sevoflurane and remifentanil after the interruption of propofol administration.

CONCLUSION

We concluded that propofol administration was the cause of increased blood pressure.
