Postoperative analgesia for the surgical correction of congenital clubfoot: comparison between peripheral nerve block and caudal epidural block.

Background And Objectives: Correction of congenital clubfoot (CCF) is associated with severe postoperative pain. Caudal epidural block associated with general anesthesia is the anesthetic technique used more often in children, but it is limited by the short duration of the postoperative analgesia. Peripheral nerve blocks are associated with a low incidence of complications and prolonged analgesia.

Epidural lumbar block or lumbar plexus block combined with general anesthesia: efficacy and hemodynamic effects on total hip arthroplasty.

Background And Objectives: Anesthesia for total hip arthroplasty (THA) is a challenge due to the advanced age and associated diseases of patients. The objective of this study was to evaluate whether the efficacy of the nociceptive blockade, secondary hemodynamic effects, difficulty to execute the technique, and influence in intraoperative bleeding of lumbar plexus block combined with general anesthesia is equivalent to epidural lumbar block in patients undergoing THA.

Methods: Patients with physical status ASA I to III were randomly separated into two groups, Epidural and Lumbar.

[Effects of epidural analgesia and continuous lumbar plexus block on functional rehabilitation after total hip arthroplasty].

Unlabelled: BAKGROUND AND OBJECTIVES: Pain after total hip arthroplasty (THA) is severe and it is aggravated by movements, which requires an effective analgesic technique that allows early mobilization, participation in rehabilitation activities, and fast functional recovery. The objective of this study was to compare the effects of epidural and perineural patient-controlled analgesia (PCA) of the lumbar plexus on functional rehabilitation of patients undergoing THA.

Methods: Patients classified as physical status ASA I to III were randomly divided into two groups: Epidural and Lumbar.

[The incidence of postoperative respiratory depression in patients undergoing intravenous or epidural analgesia with opioids].

Background And Objectives: Intravenous or epidural patient-controlled analgesia (PCA) is a safe and effective technique in the treatment of postoperative pain. However, the use of opioids is not devoid of risks,and respiratory depression represents the most feared complication. The objective of the present study was to describe the incidence of respiratory depression associated with postoperative analgesia with the intravenous or epidural administration of opioids and the characteristics of the patients who developed this complication.

Posterior lumbar plexus block in postoperative analgesia for total hip arthroplasty: a comparative study between 0.5% Bupivacaine with Epinephrine and 0.5% Ropivacaine.

Background And Objectives: Posterior lumbar plexus block promotes effective postoperative analgesia in total knee arthroplasty. Ropivacaine and bupivacaine do not show differences in analgesic efficacy when used in different peripheral nerve blocks. The objective of this study was to compare the efficacy of postoperative analgesia resulting from the administration of a single dose of 0.

When the bispectral index (bis) can give false results.

Background And Objectives: The bispectral index (BIS) is a multifactorial parameter derived from the electroencephalogram (EEG), which allows monitoring of the hypnotic component of anesthesia. It was obtained from the algorithm based on the analysis of a large number of EEGs from volunteers and patients undergoing sedation and general anesthesia with different anesthetic agents. The use of BIS to monitor the depth of anesthesia reduces the incidence of intraoperative awakening and recall, among other benefits.

[Total spinal block after posterior lumbar plexus blockade: case report.].

Background And Objectives: Lumbar plexus blockade can be very useful in surgical procedures of the hip, thigh, and knee, but it should be performed by an experienced anesthesiologist due to potential complications. The current report presents a case of total spinal block after posterior lumbar plexus blockade and discusses the possible pathophysiological mechanisms.

Case Report: Male patient, 34 years old, 97 kg, physical status ASA I, scheduled for total hip arthroplasty.

[Regression of general anesthesia in patients with cerebral palsy: a comparative study using the bispectral index.].

Background And Objectives: It has been said that patients with cerebral palsy (CP) present a higher sensitivity to anesthetic agents, which may affect adversely the awakening from anesthesia. The objective of this study was to evaluate the recovery of patients with CP compared with patients without CNS disease.

Methods: The study population was composed of children ages 5 to 15, divided in two groups: those with a diagnosis of cerebral palsy and those without CNS disease.

[Immobility: essential inhalational anesthetics action.].

Background And Objectives: Immobility is an essential component of general anesthesia and should be looked for and maintained throughout anesthesia. Anesthetic potency, called Minimum Alveolar Concentration (MAC), results from the inhibition of movement response to noxious stimulation. However, although spinal cord is recognized as the primary mediator of surgical immobility, cellular and subcelular mechanisms of action of inhaled anesthetics to produce immobility are not yet totally known.

[Continuous epidural analgesia: analysis of efficacy, side effects and risk factors.].

Background And Objectives: Epidural analgesia with local anesthetics and opioids has a reputation of high efficacy with low incidence of side effects. This study aimed at determining incidence, type and severity of postoperative complications related to epidural analgesia and catheter insertion.

Methods: Participated in this retrospective study 469 patients submitted to postoperative epidural analgesia in the period 10/18/99 to 10/18/01.
