To observe the potency ratio of hyperbaric to isobaric solutions of ropivacaine in subarachnoid block for knee arthroscopy. ⋯ The ED50 of hyperbaric ropivacaine is less than that of isobaric ropivacaine in subarachnoid block anesthesia for knee arthroscopy.

To study the effects of dexmedetomidine (Dex) on cellular immunity during the perioperative period in children with brain neoplasms. ⋯ Dex given by a continuous intravenous infusion during general anesthesia may effectively inhibit the stress responses and reduce the inhibition of cellular immunity in children with brain neoplasms during the perioperative period.

Acute pulmonary embolism (PE) is potentially a life threatening emergency that needs prompt management to reduce preventable deaths. Symptoms like dyspnoea and chest discomfort often lack specificity and overlap with acute coronary syndrome (ACS). Importantly, electrocardiographic changes associated with PE are reported to be variable with some ECG patterns mimicking ACS, posing problems in the differential diagnosis. ⋯ However, this ECG change is more likely to present in ACS. We herein reported a case of a 78-year-old man presenting with progressive shortness of breath on exertion secondary to submassive pulmonary embolism which was initially misdiagnosed as ACS due to diffuse T wave inversion in both precordial leads V1-6 and inferior Leads II, III and aVF. Here, we discussed the diagnosis of this case and reviewed the medical literature with an emphasis on the limitations of ECG for the differentiation between PE and ACS.

Locking of central venous catheters with heparin is an accepted practice to maintain catheter patency between dialysis sessions. However, this practice may cause other adverse reactions. Although many studies suggest benefits of other catheter lock solutions over heparin on these grounds, no consensus has been reached for clinical practice. ⋯ Compared with heparin, antimicrobial-containing lock solutions more effectively prevent CRB and clinical sepsis. Antibiotics + heparin and gentamicin + citrate solutions showing better prevention of CM. Citrate-alone lock solutions result in fewer CRB, bleeding and ESI episodes.
