目的 評價硬膜外麻醉合用丙泊酚用于腹腔鏡膽囊切除術的可行性。方法 擇期行腹腔鏡膽囊切除術患者850例，經T 9～10椎間隙行硬脊膜外腔穿刺置管，給予常規劑量的2%利多卡因或0.75%布比卡因，氣腹前靜脈注射丙泊酚1～2 mg/kg,直至患者意識消失，繼以10 mg/(kg·h)維持麻醉深度。結果 全組850例患者術中麻醉效果好，腹肌松弛，意識消失后避免了氣腹引起的牽扯反射，停止使用丙泊酚10 min左右時間，大部分患者即恢復呼喚反應。 結論 硬膜外麻醉合用丙泊酚用于腹腔鏡膽囊切除術是一種效果很好的臨床麻醉方法。
目的 觀察不同濃度腎上腺素與利多卡因混合液頭皮浸潤注射對開顱術患者血流動力學的影響。方法 選取2010年5月－10月80例顱內腫瘤患者，隨機分成4組，行1%利多卡因溶液混合不同濃度的腎上腺素16 mL頭皮浸潤注射。腎上腺素濃度：A組2.5 μg/mL、B組5.0 μg/mL、C組7.5 μg/mL、D組10.0 μg/mL。記錄注射前（T0）、注射后5 min內（T1-10）心率（HR）、平均動脈壓（MAP）、收縮壓（SBP）、舒張壓（DBP），根據各時段的MAP最低值和最高值，計算MAP的降低率和升高率，計數各組MAP下降10%以內、10%～20%和20%以上的例數。 結果 C組的MAP下降例數最多且MAP下降率最高，與其他組間比較差異有統計學意義（P＜0.05）。組內比較，C組MAP、SBP在1.5、2.0、2.5 min時、DBP在2 min時和D組MAP和DBP在1.5、2.0 min時下降差異有統計學意義（P＜0.05）。4組血壓下降的同時伴HR增快，但HR組間差異無統計學意義（P＞0.05）。 結論 低濃度的腎上腺素與10%利多卡因混合液用于開顱術患者頭皮浸潤注射時可導致血壓下降。
Objective To observe the changes of serum potassium level and the factors that affected it when preoperative intravenous administration of gelofusine was given rapidly at high dose. Methods Thirty patients scheduled for upper abdominal operation were selected for the study and they were randomizely divided into test group (gelofusion group) and control group with 15 cases in each group. The first blood and urine sample was taken after epidural puncture and the potassium value was used as basic values. Then an intravenous administration of gelofusion at a dose of 10ml/kg was given in gelofusion group within 30min and then the second sample was obtained. Another intravenous administration of gelofusion at a dose of 10 ml/kg was given within 1 hour and the third sample was taken, while the fourth and fifth samples were taken 30 and 90 minutes after the third samples taken respectively. All the blood samples were tested for serum level of electrolytes (Na+,K+,Cl-,Ca2+,Mg2+), pH, Osm, Hct. The value of electrolytes (Na+,K+,Cl-,Ca2+,Mg2+) of urine samples were determined too. The intracellular levels of K+ and Mg2+ of erythrocyte were tested. The gelofusion were replaced by saline solution in control group and the other procedures were the same.Results The serum level of potassium was decreased progressively after rapid intravenous administration of gelofusine at high dose. Conclusion The serum level of potassium will decrease significantly after rapid intravenous administration of gelofusion at high dose during operation.
ObjectiveTo investigate the efficacy of stellate ganglion block (SGB) on postoperative palpebral edema in patients undergoing intracranial aneurysm surgery. MethodsSixty patients who were scheduled to undergo intracranial aneurysm surgery between September 2012 and Novermber 2014 were recruited, and were assigned into 2 groups randomly with 30 in each:SGB group and control group. Patients in SGB group were administered SGB by injecting 0.3% ropivacaine on the operative side under the ultrasound guidance after surgery completed, while patients in the control group received injection of saline on the operative side under the ultrasound guidance. Incidence of postoperative palpebral edema at hour 24, 48, and 72 after surgery were measured. Numerical rating scale (NRS) was used to detect the severity of uncomfortable symptoms for palpebral swelling during rest state. The severity of palpebral edema was evaluated with continuous rating scale (0-5, 0 indicated normal palpebral, and higher score indicated more serious palpebral edema). Complications related with SGB were recorded. ResultsThe overall incidence of palpebral edema at hour 24 after surgery in SGB group was lower than that in the control group (P<0.05). There was no statistically significant difference in the overall incidence of palpebral edema at hour 48 and 72 after surgery between the two groups (P>0.05). The palpebral edema rating scores of the SGB group at hour 24 after surgery were lower than those of the control group (P<0.01).The incidence of palpebral edema which was scored 3 or more at hour 24 and 48 after surgery in SGB group was lower than that in the control group (P<0.05). No statistically significant difference was found in the incidence of palpebral edema which was scored 3 or more at hour 72 after surgery between the two groups (P>0.05). No complication related with SGB was found. ConclusionSGB can safely reduce the incidence of postoperative palpebral edema in patients undergoing intracranial aneurysm surgery, and reduce the severity of palpebral edema.
