The Hypotension Prediction Index (HPI) algorithm is a commercial prediction algorithm developed to predict hypotension, a mean arterial pressure (MAP) below 65 mmHg. Although HPI has been investigated in several studies, recent concerns of have been raised regarding HPI's predictive abilities, which may have been overstated. ⋯ This CON position paper describes the selection bias further and summarises the scientific status of HPI's predictive abilities, including the meaning of a recent erratum retracting the primary conclusion of a published HPI validation study. We argue that the HPI algorithm needs re-validation or complete re-development to achieve a clinically relevant 'added value' in comparison with the predictive performance of a simple and costless MAP alarm threshold in the range of 70 to 75 mmHg.

Randomized Controlled Trial
Epidural analgesia versus oral morphine for postoperative pain management following video-assisted thoracic surgery: A randomised, controlled, double-blind trial.
The use of thoracic epidural analgesia for postoperative pain management in video-assisted thoracic surgery (VATS) is controversial. Still, the evidence on omitting it in favour of systemic opioids is inconclusive, and studies are small and non-blinded. ⋯ Epidural analgesia provided better pain relief after VATS than oral morphine. The between-group difference in rescue intravenous morphine consumption was statistically significant but clinically irrelevant.

Randomized Controlled Trial
Duration of analgesia after forefoot surgery compared between an ankle and a sciatic nerve block at the popliteal crease: A randomised controlled single-blinded trial.
Forefoot surgery is associated with severe postoperative pain. Ankle and sciatic nerve blocks provide satisfactory postoperative analgesia after forefoot surgery, but little is known on their respective duration of analgesia. ⋯ Compared with the ankle block, the sciatic nerve block at the popliteal crease does not provide a longer duration of analgesia in patients undergoing forefoot surgery in the setting of multimodal analgesia.
