Spinal/epidural block as an alternative to general anesthesia for laparoscopic appendectomy: a prospective randomized clinical study

Regional Anaesthetic Techniques and Their Implications During the COVID Pandemic

The current pandemic has highlighted the need to protect both patients and medical staff. The increased use of regional anaesthesia as a primary anaesthetic modality for operations and other invasive procedures has limited the number of aerosol-generating procedures performed during general anaesthesia. Its use is further characterized by decreases in postoperative pain and length of hospitalization. This article provides an overview of regional anaesthetic techniques (peripheral nerve locks, epidural and spinal anaesthesia) and their uses during the COVID pandemic.

Occurrence and Severity of Catheter-Related Bladder Discomfort of General Anesthesia Plus Epidural Anesthesia vs. General Anesthesia in Abdominal Operation With Urinary Catheterization: A Randomized, Controlled Study

Background: This randomized, controlled study aimed to investigate the effect of general anesthesia plus epidural anesthesia on catheter-related bladder discomfort (CRBD) in patients who underwent abdominal operation with urinary catheterization.

Methods: A total of 150 patients scheduled for abdominal operation under anesthesia with urinary catheterization were randomized to receive general anesthesia plus epidural anesthesia (N = 74, GA + EA group) or general anesthesia (N = 76, GA group). The occurrence and severity of CRBD, systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were recorded at 0 hour (h), 0.5, 1, and 3 h after tracheal extubation. Besides, postoperative adverse events were assessed.

Results: The occurrence and severity of CRBD at 0, 0.5, 1, and 3 h were all reduced in GA + EA group compared to GA group (all P < 0.05). Meanwhile, subgroup analyses showed that the reduction of occurrence and severity of CRBD in GA + EA group compared to GA group was more obvious in male patients and patients ≥50 years. Besides, SBP at 0, 0.5, 1, and 3 h, as well as DBP at 0, 0.5, and 3 h were all decreased in GA + EA group compared to GA group (all P < 0.05), while HR was increased at 0 h in GA + EA group compared to GA group (P = 0.034). Moreover, the occurrence of pain, severity of pain and occurrence of vomiting were similar between GA + EA group and GA group (all P > 0.05).

Conclusion: General anesthesia plus epidural anesthesia decreases CRBD occurrence and severity with tolerable safety compared with general anesthesia in patients who undergo abdominal operation with urinary catheterization.

Spinal anaesthesia for a NOTES (Natural Orifice Transluminal Endoscopic Surgery) total hysterectomy in a pre-lung transplant patient : a case report

We describe the first case of a vaginal NOTES total hysterectomy under spinal anesthesia in the head- down position without sedation or additive analgesia in a patient with end-stage COPD. This report adds to the growing evidence that neuraxial techniques are a good alternative for general anesthesia in select cases for laparoscopic surgery.

Low-pressure pulmonary recruitment maneuver: equal to or worse than moderate-pressure pulmonary recruitment maneuver in preventing postlaparoscopic shoulder pain? A randomized controlled trial of 72 patients

Introduction

The pulmonary recruitment maneuver (PRM) has emerged as an effective way of reducing post-laparoscopic shoulder pain (PLSP). However, the optimal lower pressure level for a PRM to reduce PLSP has not yet been investigated.

Aim

To compare the efficacy of the low-pressure PRM with moderate-pressure PRM in preventing PLSP.

Material and methods

Seventy-two ASA I-II patients who were scheduled for gynecologic LS for non-malignant conditions were enrolled in this study. Group 1 included patients who received the PRM at a maximum pressure of 30-40 cm H₂O in a semi-Fowler position and group 2 included patients who received the PRM at a maximum pressure of 15 cm H₂O in a semi-Fowler position. The primary outcome of the study was the difference in PLSP between the two groups.

Results

There were no significant differences in PLSP and wound pain VAS scores between patients receiving the PRM at 30 cm H₂O and 15 cm H₂O during postoperative pain monitoring (p < 0.05). The groups were also similar with respect to ambulation time (p = 0.215), length of hospital stay (p = 0.556) and the height of the pneumoperitoneum measured on chest X-ray (p = 0.151).

Conclusions

The low-pressure PRM (15 cm H₂O pressure) provides similar efficacy as the moderate-pressure PRM (30-40 cm H₂O) in terms of PLSP, wound pain, height of pneumoperitoneum, time of ambulation and length of hospital stay. We suggest that lower maximal inspiratory pressure of 15 cm H₂O might be preferred to avoid the potential complications of the PRM with higher pressures.

Spinal anesthesia is a viable option for emergent laparoscopic procedure in high-risk patients

General anesthesia is the gold-standard for laparoscopic procedures. Spinal anesthesia is usually not used and hypotension and impairment of spontaneous breathing are the most feared complications. A 86-year-old patient with a history of stage four chronic obstructive pulmonary disease (FEV1 28%) underwent emergent surgery for acute abdominal pain. A combined spinal-epidural anesthesia was successfully performed, surgery lasted ninety minutes without any surgical difficulties. Patient was discharged from the hospital on the third postoperative day. Our case depicts well how spinal anesthesia may be a viable option for high risk patients undergoing emergent laparoscopic surgery.
