There is conflicting information in the literature regarding nerve damage following regional anesthesia. Intraneural injection of local anesthetic was described as a safe practice in regional anesthesia. This review focuses on the histopathological and functional assessment of peripheral nerve function following intraneural injection of local anesthetics.

Various options are available for the provision of analgesia following major surgical procedures including systemic opioids and regional anesthetic techniques. Regional anesthetic techniques offer the advantage of providing analgesia while avoiding the deleterious adverse effects associated with opioids including nausea, vomiting, sedation and respiratory depression. Although used commonly in infants and children, there is a paucity of experience with the use of caudal epidural blockade in adolescents. ⋯ Our preliminary experience demonstrates the efficacy of caudal epidural block in providing analgesia following major urologic and orthopedic surgical procedures. The applications of this technique as a means of providing postoperative analgesia are discussed.

Transversus abdominis plane (TAP) block is suitable for lower abdominal surgeries. Blind TAP block has many complications and uncertainty of its effects. Use of ultrasonography increases the safety and efficacy. This study was conducted to evaluate the analgesic efficacy of ultrasound (USG)-guided TAP block for retroperitoneoscopic donor nephrectomy (RDN). ⋯ The USG-guided TAP block is easy to perform and effective as a postoperative analgesic regimen in RDN, with opioids-sparing effect and without any complications.

The choice of an ideal fluid administered post trauma and its subsequent influence on coagulation still poses a clinical dilemma. Hence, this study was designed to assess the influence of in vivo hemodilution with various fluid preparations (4% gelatin, 6% hydoxyethyl starch (HES), Ringer's lactate, 0.9% normal saline) on coagulation using standard coagulation parameters and real-time thromboelastography (TEG) in patients undergoing elective surgery post trauma. ⋯ Crystalloids are optimal volume expanders in trauma, with RL having beneficial effects on coagulation system (decrease in k time and increase in MA and A20). Among the colloids, HES 6% (130/0.4) affects coagulation parameters (increase in PTI, INR, R time, k time) more than gelatin. Trial registration (protocol number-IEC/NP-189/2011).

Paravertebral block (PVB) has been an established technique for providing analgesia to the chest and abdomen. We conducted the current study to compare single-dose PVB versus single-dose epidural blockade (EP) for pain relief after renal surgery. ⋯ Single injection PVB resulted in similar analgesia but greater hemodynamic stability than epidural analgesia in patients undergoing renal surgery, therefore this technique may be recommended for patients with coexisting circulatory disease.
