Objective Marker

The relationship between the change of pulse transit time and the presence of clinical signs after stallate ganglion block (SGB) was investigated in patients with disorders mediated by the sympathetic nervous system. SGB is used for the treatment and diagnosis of these disorders; however, a successful objective marker does not exist. Therefore, identifying increased blood flow following SGB and determining whether pulse transit time could be used to verify the success of SBG would be a helpful resource.BACKGROUND: An objective marker of successful stellate ganglion block (SGB) does not exist. Horner syndrome, which is currently used to determine the effect of SGB, is sometimes ambiguous.OBJECTIVE: To investigate the change in pulse transit time (PTT) after SGB, and to evaluate the utility of PTT as an objective measure of successful SGB.METHODS: Eight patients (34 to 62 years of age) underwent SGB for diagnosis or treatment of sympathetically mediated pain of the upper extremities. The success of the SGB was determined according to the presence of Horner syndrome. Electrocardiography, noninvasive blood pressure measurements and pulse oximetry were used to monitor all patients. PTT was measured using data saved on the WinDaq waveform browser.RESULTS: PTT was measured at baseline and 3 min, 5 min and 10 min after the injection of a local anesthetic. At 3 min after SGB, the mean (± SD) PTT was 624.6±20.5 ms. At 5 min after injection, the mean PTT was 630.8±17.5 ms. Prolonged PTT at 5 min was found to return to the baseline value at 10 min (613.6±14.7 ms). According to the Friedman test, the differences from baseline values were significant (P=0.008).CONCLUSION: Measurement of PTT at 5 min after local anesthetic injection can help to objectively determine the success of SGB.

Abstract Background: The return of normal gastrointestinal function is an important signal of postoperative recovery in patients undergoing surgery with general anaesthesia, especially for abdominal surgery. Current methods to resolve this problem are conservative, and the effects are sometimes limited. We aimed to summarize the effects of stellate ganglion block(SGB) on the recovery of gastrointestinal function to explore methods for anaesthesiologists to contribute to postoperative patient recovery. RuMethods: Selected databases were searched for relevant studies. Study quality was assessed according to the Cochrane Collaboration’s tool for assessing risk of bias. Data extraction was performed independently. The time to peristaltic sound resumption, flatus, postoperative eating and the incidence and degree of abdominal bloating were compared between stellate ganglion and control groups. Meta-analysis was performed using Review Manager software. Results: In total, 281 studies were identified after searching for relevant articles, and five articles with data for 274 patients were eligible for this analysis. Regarding postoperative flatus time, SGB caused a mean reduction of 15 hours for different surgeries; after excluding a study causing heterogeneity, the mean reduction was still more than 6 hours. For gastrointestinal surgery, the mean reduction was approximately an entire day. When evaluating the recovery of peristaltic sounds in different surgeries, SGB promoted the recovery of regular bowl sounds by an average of 14.67 hours earlier than the control. With regard to nutrients, SGB shortened the total parenteral nutrition time by more than 50 hours in gastrointestinal surgery. Finally, SGB prevented the occurrence of postoperative abdominal bloating without influencing its degree. No complications related to SGB were reported. Conclusion: SGB promotes postoperative gastrointestinal recovery in patients undergoing different surgeries with general anaesthesia.

Background: Because it affords greater accuracy than landmark-based techniques, ultrasound guidance may reduce the volume of local anesthetic required for sympathetic blockade of the upper extremity. We hypothesized that 4 mL would provide a similar clinical effect when compared to larger volumes. Methods: One hundred and two patients with chronic neuropathic pain of the upper extremity or face were randomly assigned to receive an ultrasound-guided (USG) stellate ganglion block (SGB) with either 4 mL (group A), 6 mL (group B) or 8 mL (group C) mL of 1.0% lidocaine. Skin temperatures of the face, hand, and axillary fold were measured bilaterally at baseline, 10, 20, and 30 min after the block. Our primary outcome was the relative increase in hand temperature on the blocked side at 30 min and our non-inferiority margin was −0.6 °C. Secondary outcomes included success rate (as defined by a relative temperature increase of ≥1.5 °C), pain relief, degree of ptosis and side-effects. Results: The 95% confidence intervals for the difference of the means exceeded our non-inferiority margin (A versus B: −0.76 to 0.24; A versus C: −0.89 to 0.11) for temperature changes in the hand; however, success rates were similar (44, 45 and 55% for A, B and C respectively, p = 0.651). No intergroup differences were found in temperature-related outcomes for the other measurement sites (face, axilla). The incidence of minor side-effects was significantly higher in group C and no block-related complications were noted. Conclusions: We were unable to establish the non-inferiority of a 4 mL volume for sympathetic blockade of the hand. The clinical significance of these findings is unclear as success rates were similar between the different groups. In contrast, the 6- and 8 mL volumes were not associated with greater temperature changes in the face and axilla.
