“…However, additional equipment, personnel, and medical costs limit the popularization of the technology. Although patients with local anesthesia retain consciousness, previous studies have shown that analgesia is insufficient [ 8 ], and various analgesic drugs are needed to remedy [ 9 , 10 ]. Epidural anesthesia can also retain the consciousness of patients and provide perfect analgesia.…”

Background. Epidural anesthesia used in percutaneous endoscopic lumber discectomy (PELD) has the risk of complete neurotactile block. Patients cannot timely respond to the operator when the nerve is touched by mistake, so the potential risk of nerve injury cannot be avoided. According to pharmacodynamics, with the decrease of local anesthetic concentration, the nerve tactile gradually recovered; however, the analgesic effect also gradually weakened. Therefore, it is necessary to explore an appropriate concentration of local anesthetics that can keep the patients’ nerve touch without pain. By comparing the advantages and disadvantages of 0.4% ropivacaine epidural anesthesia, local anesthesia and intravenous anesthesia on intraoperative circulation fluctuation, the incidence of salvage analgesia and the incidence of nerve non-touch, the feasibility of using low concentration epidural anesthesia in PELD to obtain enough analgesia and avoid the risk of nerve injury was confirmed. Methods. 153 cases of intervertebral foramen surgery from October 2017 to January 2020 were selected and divided into local anesthesia group (LA group), 0.4% ropivacaine epidural anesthesia group (EA group), and intravenous anesthesia group (IVA group) according to different anesthesia methods. The changes of blood pressure and heart rate, the incidence of rescue analgesia and nerve root non-touch were compared among the three groups. Results. The difference of map peak value among the three groups was statistically significant ( P < 0.001 ); pairwise comparison showed that the map peak value of the LA group was higher than that of the EA group ( P < 0.001 ) and IVA group ( P < 0.001 ), but there was no statistical significance between the EA group and IVA group. The difference of HR peak value among the three groups was statistically significant; pairwise comparison showed that the HR peak value of the LA group was higher than that of the EA group ( P < 0.001 ) and IVA group ( P < 0.001 ), but there was no statistical significance between the EA group and IVA group. There was significant difference in the incidence of intraoperative hypertension among the three groups ( P < 0.05 ); pairwise comparison showed that the incidence of intraoperative hypertension in the EA group was lower than that in the LA group ( P < 0.05 ), while there was no significant difference between the IVA group, EA group, and LA group. There was significant difference in the incidence of rescue analgesia among the three groups ( P < 0.01 ); pairwise comparison showed that the incidence of rescue analgesia in the EA group was lower than that in the LA group ( P < 0.05 ) and IVA group ( P < 0.05 ), but there was no significant difference between the LA group and IVA group. Due to the different analgesic mechanisms of the three anesthesia methods, local anesthesia and intravenous anesthesia do not cause the loss of nerve tactile, while the incidence of nerve tactile in 0.4% ropivacaine epidural anesthesia is only 2.4%, which is still satisfactory. Conclusion. Epidural anesthesia with 0.4% ropivacaine is a better anesthesia method for PELD. It not only has a low incidence of non-tactile nerve, but also has perfect analgesia and more stable intraoperative circulation.

“…However, in the T group, the incidence of ∆SPI >15 was the lowest and occurred in only 13 cases (37.1%). This stands in opposition to various studies available in the literature, which showed an inability of topical anaesthesia to prevent discomfort or pain upon trocar insertion [ 26 ].…”

Vitreoretinal surgery (VRS) is one of the most widely performed precise procedures in ophthalmic surgery; the majority of cases are carried out under regional anaesthesia (RA) only. However, in specific situations (such as when the patient fails to cooperate with the operator for various reasons), general anaesthesia (GA), alone or in combination with GA (combined general–regional anaesthesia, CGR), is the only safe way to perform VRS. While monitoring the efficacy of an intraoperative rescue opioid analgesia (IROA) during surgery (assessing the adequacy of anaesthesia (AoA)) may be challenging, the surgical pleth index (SPI) is a useful tool for detecting the reaction to noxious stimuli and allows for the rational titration of opioid analgesics (AO) during surgery. The current study investigated the influence of the SPI-based titration of fentanyl (FNT) in combination with various pre-emptive analgesia (PA) techniques on intraoperative pain perception during various stages of VRS performed under AoA. A total of 176 patients undergoing VRS under GA were enrolled in the study. They were randomly assigned to one of the five following study arms: Group GA (control group)—patients who received general anaesthesia alone; Group PBB—GA with preprocedural peribulbar block (with 0.5% bupivacaine and 2% lidocaine); Group T—GA with preventive, topical 2% proparacaine; Group M—GA with a preprocedural intravenous infusion of 1.0 g of metamizole; and Group P—GA with a preprocedural intravenous infusion of 1.0 g of paracetamol. The whole procedure was divided in four stages: Stage 1 and 2—preoperative assessment, PA administration, and the induction of GA; Stage 3—intraoperative observation; Stage 4—postoperative observation. the SPI values were monitored during all stages. The occurrence of nociception (expressed as ∆SPI >15) during various manipulations in the surgical field was observed, as were cumulative doses of rescue analgesia, depending on the PA administered. During the course of VRS, rescue FNT doses varied depending on the stage of surgery and the group investigated. The majority of patients, regardless of their group allocation, needed complementary analgesia during trocar insertion, with Group GA patients requiring the highest doses. Likewise, the highest cumulative doses of IROA were noted during endophotocoagulation in Group GA. Preventive PBB and topical anaesthesia were proven to be most efficient in blunting the response to speculum installation, while topical anaesthesia and paracetamol infusion were shown to be more efficient analgesics during endophotocoagulation than other types used PA. In the performed study, none of the PA techniques used were superior to GA with FNT dosing under the SPI with respect to providing efficient analgesia throughout the whole surgery; there was a necessity to administer a rescue OA dose in both the control and investigated groups.

“…Another observation study by Fan et, al. demonstrated that intramuscular injection of morphine prior to PELD turns out to be overall effective, except for the increased risk of nausea and vomiting[26]. Our study is the first clinical trial to investigate the effect of ITM, a time-tested analgesia approach, as an adjuvant pain-relieving therapy on PELD.…”

BackgroundPercutaneous endoscopic lumbar discectomy (PELD), a minimally invasive spinal technique for lumbar disc herniation (LDH), has gained popularity globally and yielded satisfying results. However, PELD is often performed on awaking patients to avoid nerve injury, thus the intraoperative analgesia of PELD is sometimes insufficient. The effect of intrathecal morphine (ITM) has been well proved in various surgical specialties, and this study aims to investigate the effectiveness and safety of ITM on PELD.MethodsThe intrathecal morphine for percutaneous endoscopic lumbar discectomy (IMPELD) trial is a double-blind, randomized, placebo-controlled trial. The 90 eligible LDH patients undergoing PELD will be randomly assigned to receive either ITM or placebo during spinal anesthesia, at a 1:1 ratio, with a one-month follow-up period. Average intraoperative pain intensity will be the primary outcome. Secondary outcome measures include intraoperative pain intensity assessed at each 30 min intraoperatively, postoperative pain intensity, perioperative analgesia requirements, functional evaluation, radiographic characteristics, overall satisfaction, other characteristics and adverse events.DiscussionCurrently, there is a lack of scientific evidence to provide a reliable method to reduce intraoperative pain of PELD. The IMPELD trial was designed to provide evidence regarding whether 100 ug of ITM is an effective and safe coanalgesic approach for PELD procedure.Trial registrationThe trial was registered with the Chinese Clinical Trial Registry (identifier ChiCTR2000039842). Registered on November 11th, 2020.
