Effect of transcutaneous acupoint electrical stimulation on stress in brain surgery with propofol target controlled infusion general anesthesia / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To study the effect of transcutaneous acupoint electrical stimulation (TAES) on stress who received propofol target controlled infusion (TCI) general anesthesia in brain surgery.</p><p><b>METHODS</b>Totally 40 neurosurgical patients of I-II grade (ASA grading) in our hospital were randomly divided into the TAES group (T group) and the control group (C group), 20 in each group. All patients received intravenous anesthesia by propofol TCI. The TAES intervention was adopted in those of C group. Electrodes were only applied to corresponding acupoints without electric stimulation. The arterial blood was withdrawn before TAES (T0), before anesthesia (T1), before cutting (T2), at 60 min after encephalic incision (T3), immediately after incisions suture (T4), at about 10 min after removing tracheal catheters (T5) to detect beta-endorphin (beta-EP), cortisol (COR), adrenalin (E), blood sugar (Glu). The heart rate (HR) and mean arterial pressure (MAP) were recorded. The total time of surgery, anesthesia, total infusion amount, blood lost amount, and urine amount were recorded.</p><p><b>RESULTS</b>In both groups, HR, MAP, COR, and E at T2 were lower than at T0 significantly (P < 0.05). beta-EP in group C at T2 was lower than at T0 significantly (P < 0.05). HR, MAP, COR in group C at T3 were higher than at T0 significantly (P < 0.05). HR, MAP, E, and Glu in group C at T4 and T5 were higher than at T0 significantly (P < 0.05). beta-EP in group T at T1 and T3 were higher than at T0 significantly (P < 0.05). HR, COR, E, Glu, and beta-EP in group T at T4 and T5 were higher than at T0 significantly (P < 0.05). Between groups, comparing with the time point T0, the amplitude of variation of MAP, COR, and E at T2 in group C were significantly less (P < 0.05); the amplitude of variation of HR, MAP, and COR at T3 in group C were less significantly, when compared with the time point T0 (P < 0.05); the amplitude of variation of HR, MAP, COR, E, and Glu at T4 and T5 in group C were less significantly, when compared with the time point T0 (P < 0.05). When comparing the two groups, the amplitude of variation of beta-EP at time points of T1, T3, T4, and T5 in group T were larger than at T0 in group C (P < 0.05).</p><p><b>CONCLUSION</b>TAES could reduce stress and stabilize the internal environment when used in brain surgery with propofol TCI general anesthesia.</p>

Laser treatment of port wine stains / 中华整形外科杂志

<p><b>OBJECTIVE</b>To assess the efficiency of the PDL in the treatment of PWS in Chinese patients with skin type III-IV.</p><p><b>METHODS</b>252 patients with PWS at different anatomical sites were retrospectively studied. A flashlamp-pumped pulsed dye laser was used. The differences in therapeutic effect of laser were analyzed in the following ways: (1) by dermatomal distribution of face and neck; (2) by anatomical subdivision of face; (3) by the size of the lesion. The therapeutic effect was graded as 0 < or = poor < 25%, 25% < or = fair < 50%, 50% < or = good < 75%, 75% < or = excellent < or = 100%.</p><p><b>RESULTS</b>It revealed that the lesions at neck had the best response. The dermatome II zone showed the least response to PDL. Among the anatomical subdivision of face, the frontal area had the highest clearance, while the zygoma and cheek had the lowest clearance. Patients with PWS on the extremities respond less favorably with the fair lightening effect. Furthermore, the mean lightening was decreased as the size of PWS was increased.</p><p><b>CONCLUSIONS</b>The response difference of PWS to PDL was not only related to the anatomical region, but also related to the lesion size. It is imperative to give the patients rational treatment suggestion and normal expectation.</p>

Secondary reconstruction of post-fracture deformities in the nasal-orbital ethmoid region / 中华整形外科杂志

<p><b>OBJECTIVE</b>To study the surgical reconstruction of secondary fracture deformities of the nasal-orbital ethmoid area.</p><p><b>METHODS</b>Typical bicoronal and subciliary incisions or the adjacent scar incision were employed to expose the fractured area. The flattened nasal bone was narrowed by curved osteotomy along the medial orbital rims and trimed with a bur. 2-3 pieces of cranial outer table were used to reconstruct the nasal framework, which were fixed to the frontal bone with mini-plates. After the medial orbital wall and orbital floor were exposed, the herniated orbital contents were released and reduced to the orbital cavity. The fractured orbital walls were repaired precisely with autogenous cranial outer table or Medpor. The medial canthal tendons were anchored superior-posteriorly to the lacrimal fossa with transnasal wires.</p><p><b>RESULTS</b>From December 1996 to December 2001, 34 cases of severe nasal-orbital ethmoid fracture deformities were repaired with this technique. Of them, 12 cases had combined orbital-zygomatic fracture, 4 cases had fontal sinus fracture, 1 case had Le Fort II and 1 case had Le Fort III fracture. All the patients recovered well and their facial appearance improved greatly.</p><p><b>CONCLUSIONS</b>The key points for surgical reconstruction of the periorbital post-fracture deformities are narrowing the flattened nasal root by curved osteotomy, the nasal framework reconstruction with autogenous bone graft, the orbital wall repair to correct enophthalmos, and most importantly, the medial canthal tendon reduction and canthal plasty.</p>
