Preoperative planning of primary total hip arthroplasty using conventional radiographs.

Objective: the objective of this study was to present an analog method for preoperative planning of primary total hip arthroplasty procedures based on measuring the components by overlaying the transparencies of the prosthesis on the preoperative radiographs and checking the accuracy, both for predicting the size of the acetabular and femoral components used and for restoring the offset and correcting the dysmetria.

Methods: between March 2005 and July 2009, 56 primary total hip arthroplasty procedures performed on 56 patients at the Mario Covas State Hospital in Santo André were analyzed. The measurements on the femoral and acetabular components obtained through planning were compared with those that were used in the surgery.

Tomographic index as auxiliary criteria for surgery indication in fracture dislocation of acetabulum posterior wall.

There are situations which the tomographic exam is done on the affected hip or situations where the contralateral hip presents abnormalities that make it impossible to compare. In this study we aimed to evaluate a tomographic index that does not require comparison between the both hips. Twenty two patients with unilateral acetabular fracture dislocation with fracture of posterior wall were studied.

[Oxytocin in cesarean sections: what is the best way to use it?].

Background And Objectives: Oxytocin is the uterotonic used in obstetric anesthesia, and its prophylactic and therapeutic administration is justified because it reduces the incidence of post-partum hemorrhage. However, the ideal infusion regimen in elective cesarean sections has not been determined yet. The objective of this study was to review the main physiological and pharmacological characteristics of oxytocin and to discuss its rational use by anesthesiologists in view of its side effects.

[Anesthesia breathing systems with CO2 absorption, circle valve circuit: comparison of thermal behavior of coaxial system and conventional system with different fresh gas flows.].

Background And Objectives: The adequate maintenance of inhaled gases temperature during anesthetic procedures is critical to prevent perioperative respiratory complications. This study aimed at comparing the ability to warm up inhaled gases of coaxial breathing system and conventional system, by varying fresh gas flows (FGF).

Methods: Breathing systems were tested in a lung simulator ventilated with 600 mL tidal volume and respiratory frequency of 10 bpm.

[Spinal sufentanil associated to hyperbaric bupivacaine: Is it possible to decrease opioid dose?].

Background And Objectives: The association of isobaric bupivacaine to lower spinal sufentanil dose provides satisfactory analgesia and lower incidence of side effects. This study aimed at evaluating quality of analgesia and incidence of side effects of decreased spinal sufentanil doses associated to hyperbaric bupivacaine for labor analgesia.

Methods: Participated in this study 69 healthy term pregnant patients in active labor.

Fluid preload in obstetric patients. How to do it?

Background And Objectives: In has been shown in non-obstetric patients, that a fast acute fluid preload immediately after spinal anesthesia was more effective than a slow preload before regional block to decrease the incidence and severity of arterial hypotension after spinal anesthesia. This study aimed at comparing the incidence of arterial hypotension and vasopressants consumption in parturients submitted to C-section under spinal anesthesia with different fluid preload regimens.

Methods: Sixty term pregnant women submitted to C-section under spinal anesthesia.

[Post-cesarean section analgesia with low spinal morphine doses and systemic nonsteroidal anti-inflammatory drug: diclofenac versus ketoprofen.].

Background And Objectives: The association of low spinal morphine doses and muscular diclofenac is effective to control postoperative pain after Cesarean section under spinal anesthesia. Ketoprofen, also an NSAID, may be advantageous over diclofenac because it may be intravenously administered. This study aimed at comparing the analgesic efficacy of diclofenac and ketoprofen in association to low spinal morphine doses in the immediate postoperative period of patients submitted to Cesarean section under spinal anesthesia.
