Randomized Controlled TrialEfficacy of Ultrasound-Guided Transversus Thoracic Muscle Plane Block on Postoperative Opioid Consumption After Cardiac Surgery: A Prospective, Randomized, Double-Blind Study.
The postoperative analgesic efficacy of transversus thoracic muscle plane block (TTMPB) has not yet been evaluated sufficiently. This randomized controlled study evaluated the effect of TTMPB on postoperative opioid consumption in patients undergoing cardiac surgery. ⋯ A single preoperative TTMPB provided effective analgesia and decreased opioid requirements in patients undergoing cardiac surgery.

Observational StudyDistribution of injectate administered through a catheter inserted by three different approaches to ultrasound-guided thoracic paravertebral block: a prospective observational study.
Despite the popularity of continuous thoracic paravertebral block (TPVB), there is a paucity of information on catheter tip position and distribution of injectate through the catheter. We observed, in real time, the spread of dye, the catheter tip position and sensory block levels produced with three different (intercostal (IC), transverse process sagittal (TS) and paralaminar (PL)) approaches to ultrasound-guided TPVB in patients undergoing video-assisted thoracoscopic surgery. ⋯ Although a bolus injection through a catheter for ultrasound-guided TPVB produced multiple levels of spread and sensory blockade in more than half the patients, considerable differences existed in the spread regardless of approach.

Analgesia for postoperative myomectomy pain: A comparison of ultrasound-guided transversus abdominis plane block and wound infiltration.
Acute postoperative pain after myomectomy can impair patient function. Like all other postoperative pain, it is a challenge requiring solution, particularly in developing countries. Ultrasound-guided transversus abdominis plane (TAP) block and wound infiltration (WI) are both known to be effective in managing postoperative pain. It is not certain if transversus abdominis plain block would be superior to wound infiltration. Aims: It was hypothesized that the TAP block has similar analgesic effectiveness to wound infiltration. ⋯ TAP block provided a longer duration of analgesia and a clinically superior quality of analgesia to wound infiltration.

Research into cervical spinal pain syndromes has indicated that the cervical facet joints can be a potent source of neck pain, headache, and referred pain into the upper extremities. There have been multiple diagnostic accuracy studies, most commonly utilizing diagnostic facet joint nerve blocks and an acute pain model, as Bogduk has proposed. Subsequently, Manchikanti has focused on the importance of the chronic pain model and longer lasting relief with diagnostic blocks. ⋯ Based on this investigation, utilizing a chronic pain model, there was significant difference in the relief patterns. This assessment showed prevalence and false-positive rates of 49.3% and 25.6% in chronic neck pain. Duration of relief >= 80% pain relief was 6 days with lidocaine and 12 days with bupivacaine, with total relief of >= 50% of 31 days with 55 days respectively.
