An electronic device (Episensor) for detection of the interpleural space.
Complications associated with interpleural block are often related to difficulty with needle and catheter placement. Thus there exists need for refinement of the puncture technique. We present our initial experience identifying the interpleural space with a new electronic detector (Episensor, Palex, Spain) that is sensitive to negative pressure. Twenty-five patients undergoing cholecystectomy (subcostal incision), nephrectomy or mastectomy were included in the study. All patients had an interpleural catheter placed after completion of surgery, but before extubation, using the Episensor. The technique was successful in all cases. The mean time from needle insertion to taping the catheter to the skin was 6.3 +/- 3.6 minutes. No patient developed a pneumothorax. Four patients (16%) complained of chest pain during the interpleural injection of radiopaque medium. Pain relief during the 48-hour observation period was good. Supplemental analgesia was required in nine nephrectomy patients. We believe the Episensor may be a valuable adjunct to the initiation of interpleural anesthesia.

[Tremor and epidural anesthesia].
To evaluate the influence of temperature of the injected anesthetic solution on the development of tremor during epidural anesthesia, 66 patients divided in three homogeneous groups were evaluated: group I (n = 22; bupivacaine 4 degrees C), group II (n = 24; bupivacaine 20 degrees C), and group III (n = 24; bupivacaine 37 degrees C). The incidence of tremor was 20% (4 patients) in group I, 9% (2 patients) in group II and 12.5% (3 patients) in group III. No significant differences were found between the groups. The overall incidence was 13.6%. The epidural injection of 5 ml of saline at 37 degrees C achieved the attenuation and/or disappearance of tremor in three (3/4) group I patients (4 degrees C) and in one (1/3) group III patient (37 degrees C), whereas it was ineffective in one patient from group I and one from group III. In the two patients from group II (20 degrees C) and in one from group III (37 degrees C), tremor was self-limited. We conclude that the incidence of tremor during epidural anesthesia is not correlated with the temperature of anesthetic solutions, and that the epidural injection of saline at 37 degrees C may give some therapeutic benefit.

[Nitroglycerin spray in the prevention of hypertension induced by electroconvulsive therapy].
The aim of this study was to determine if 0.4 mg of nitroglycerin (NTGs) administered by sublingual route in spray before the electroconvulsive therapy (ECT), attenuated the associated hypertensive response. In 21 patients who were between 17 and 77 years old, 81 sessions of ECT were performed. NTGs was administered in 38 sessions. The rest 43 sessions was considered control group. In the control group ECT caused a significant increase of systolic blood pressure (SBP) and diastolic blood pressure (DBP) (p less than 0.05) when compared with basal values. In NTGs group the increase of SBP and DBP was not significant when compared with basal values. Those changes were mainly observed in patients over 45 years old. In conclusion, 0.4 mg of NTGs significantly attenuate the hypertensive response that is caused by ECT in patients over 45 years old.
