Clinical TrialMeasurement of intraocular pressure during laparoscopy and its relationship to central venous pressure.
STUDY OBJECTIVE. To determine the effect of different positional degrees on hemodynamics, especially central venous pressure and intraocular pressure, and a possible interrelationship, during laparoscopic surgery. SETTING. University teaching hospital (Canadian Task Force classification II-1). ⋯ Continuous monitoring of intraocular pressure may help detect alterations in central venous pressure during general anesthesia for laparoscopic surgery. Undesirable alterations caused by degree of Trendelenburg position may negatively affect patients with high cardiac or ophthalmic risk.

Randomized Controlled Trial Clinical TrialPain control after microlaparoscopy.
To evaluate the efficacy of intraperitoneal subdiaphragmatic instillation of 0.5% lidocaine and 0.5% bupivacaine infiltration of cannula sites to control pain after diagnostic microlaparoscopy. ⋯ Postoperative intraperitoneal lidocaine and bupivacaine infiltration of cannula sites offered a detectable benefit to women undergoing diagnostic microlaparoscopy. The effect was temporary, but induced a significant decrease in the postoperative pain for approximately 6 hours.

Comparative Study Clinical TrialLaparoscopic appraisal of the anatomic relationship of the umbilicus to the aortic bifurcation.
To determine the cephalocaudal relationship among the umbilicus, aortic bifurcation, and iliac vessels by direct measurement during laparoscopy. ⋯ The cephalocaudal relationship between the aortic bifurcation and umbilicus varies widely and is not related to body mass index in anesthetized patients. Regardless of body mass index, the aortic bifurcation is more likely to be located caudal to the umbilicus in the Trendelenburg compared with the supine position. Its presumed location can be misleading during Veress needle or primary cannula insertion, and a more reliable guide is necessary for this procedure to avoid major retroperitoneal vascular injury.
