The ultimate technique for posterior rib fractures: the parascapular sub-iliocostalis plane block - A series of cases

We report retrospectively a series of four cases involving the successful use of the recently described parascapular sub-iliocostalis plane block (PSIP), for lateral-posterior rib fractures. The efficacy of the PSIP block may potentially depend on different mechanisms of action: (1) direct action in the fracture site by craniocaudal myofascial spread underneath the erector spinae muscle (ESM); (2) spread to deep layers through tissue disruption caused by trauma, to reach the proximal intercostal nerves; (3) medial spread below the ESM, to reach the posterior spinal nerves; and (4) lateral spread in the sub-serratus (SS) plane to reach the lateral cutaneous branches of the intercostal nerves; while avoiding significant negative hemodynamic effects and other possible complications associated to other techniques leading that the PSIP may be considered an alternative in some clinical scenarios to the Erector Spinae Plane block or the Paravertebral block.

A comparative study between ultrasound-guided thoracic paravertebral block, pectoral nerves block, and erector spinae block for pain management in cancer breast surgeries. A randomized controlled study

OBJECTIVES

Achieving adequate perioperative analgesia can be challenging in patients undergoing breast surgeries due to the complex nerve supply of the breast and axilla. The study aims to investigate the efficacy of ESPB in comparison to conventional regional anesthesia techniques (TPVB and PECS).

METHODS

Eighty female patients who were scheduled for elective MRM, with ASA score I-II, and aged between 18 and 60 years, were included in the study. Patients were randomized into four groups, the TPVB, PECS, ESPB, and the control group. All patients in either block groups received 25 ml bupivacaine 0.25% with ultrasound guidance. The control group received only opioids for perioperative pain management. The patients were observed for 48 h after surgery for the duration of analgesia (primary outcome).

RESULTS

ESPB has a shorter duration of analgesia than PECS block with no significant statistical difference compared with group TPVB. Morphine consumption is increased in ESPB compared to the PECS group, with an insignificant difference compared to group TPVB. There was an insignificant difference between the groups concerning hemodynamics and complications, with one pneumothorax case reported in the TPVB group.

CONCLUSION

PECS and ESPB represent a good alternative to TPVB for post-mastectomy analgesia with a superior analgesic effect of PECS block regarding opioid consumption, duration of the analgesia, and VAS score.

Ultrasound-guided clavipectoral fascia plane block for middle third clavicular fracture: A case series

BACKGROUND AND OBJECTIVE

Clavipectoral fascia plane block has been described as an anaesthetic and analgesic strategy for osteosynthesis of midclavicular fractures. However, to date, only isolated cases have been published. The aim of this study was to evaluate the anaesthetic and analgesic efficacy of this new approach in midclavicular fracture surgery in a large case series.

MATERIAL AND METHODS

Descriptive, observational study of 50 patients undergoing osteosynthesis of middle third clavicular fracture who received CPB block associated with supraclavicular nerve block. The primary objective was to assess pain on a VAS scale in the immediate postoperative period, and at 6, 12 and 24h. Secondary objectives were to determine the degree of intraoperative sedation, perioperative morphine consumption, need for rescue analgesia, unplanned general anaesthesia, presence of motor and sensory blockade, and diagnosis of diaphragmatic paralysis.

RESULTS

Postoperative pain was 1.04 (SD=1.26) in the immediate postoperative period; 1.24 (SD=1.42) at 6h; 1.34 (SD=1.92) at 12h; and 0.96 (SD=1.29) at 24h. Mean total intraoperative fentanyl dose was 0.88μg/kg. Postoperatively, nine patients (18%) requested rescue analgesia. There were no conversions to general anaesthesia, no motor or sensory blockade of upper extremities, and no hemidiaphragmatic paralysis.

CONCLUSIONS

Our series supports the anaesthetic and analgesic efficacy of CPB block for osteosynthesis of midclavicular fractures.

[Clinical practice guideline for the treatment of spasticity: Consensus and algorithms]

Spasticity is a complex phenomenon of extremely variable clinical expression, a dynamic and evolutionary process that can condition the activity and treatment of the patient. The current recommendation for early treatment aims to avoid progression and complications, and involves an individualized approach based on a wide range of pharmacological and non-pharmacological measures. This guide results from a forum of expert specialists who faced some frequent uncertainties in the assessment process and therapeutic approach of the spastic patient such as the suitability of initiating treatment, considerations for initiating, continuing and ceasing treatment with botulinum toxin, adjuvant treatments, pain or follow-up. The result is one algorithm of decision for the therapeutic approach of spasticity. Both scientific progress and the exchange of clinical experience on which this guide is based, can support decision-making on some areas of gloom that we find in daily practice.

[Radial nerve entrapment in the spiral groove. Nerve block as a diagnostic and therapeutic tool]

The radial nerve has a long and sinuous course in the upper limb from the axilla to the hand and fingers. There are several possible areas of compression along this trajectory, the most frequent being on the Arcade of Frohse, with entrapment of its terminal nerve, the posterior interosseous nerve. We report the case of a patient with radial nerve entrapment in the spiral groove and describe how ultrasound and nerve blocks could be useful in diagnosis and treatment. In our patient, nerve block at the main radial nerve in the spiral groove was insufficient. A second nerve block was needed in the inferior lateral cutaneous nerve of the arm to achieve an optimal clinical result.

[Proposal for approach to selective tibial nerve block in spastic patient. A propos of a case]

The most frequent pattern of spasticity in the lower limb is equinovarus foot. Patients with central nervous system injury and severe spasticity, conservative treatment and botulinum toxin type A often have a limited effect. In these cases, nerve blocks can be very useful in deciding our therapeutic action. We present a clinical case as an example of a new ultrasound-guided approach to tibial nerve block, as this is the main nerve involved in equinovarus foot pattern, specific for spastic patients and its usefulness for the clinical management of spasticity.

Sonotherapy in the reduction of anxiety and postoperative pain in patients with regional anesthesia as a sole technique: randomized, controlled clinical trial

Objective

To determine if sonotherapy reduces the anxiety level and postoperative pain in adults undergoing outpatient orthopedic surgery under regional anesthesia.

Method

A randomized, double-blind, placebo-controlled study in 80 adult patients undergoing orthopedic surgery, 40 received intervention with sonotherapy and 40 did not receive it. Pain, anxiety in the preoperative period, immediate postoperative, high, 24 and 48 hours later were measured. Hemodynamic parameters were measured in four moments.

Results

No significant differences were found between the two groups in the pain scales neither anxiety. A significant reduction of the systolic blood pressure was observed after the application of sonotherapy and in recovery. There was no difference in other hemodynamic variables such as heart rate, respiratory rate, arterial oxygen saturation or diastolic blood pressure between groups, however, the observed changes in some of them occurred faster in the intervention group.

Conclusions

In adult patients undergoing outpatient orthopaedic surgery under regional anaesthesia, sound therapy is a novel strategy that significantly reduces systolic blood pressure, considered as an indicator of decreased anxiety. However, in our study, no difference could be demonstrated in terms of pain control or the need for additional sedation or analgesia.

Prospective, randomized comparative study of ultrasound-guided blocking of the lateral cutaneous branches of the intercostal nerves versus conventional analgesia in non-reconstructive breast surgery

OBJECTIVE

The objective of this study is to determine whether the accomplishment of an interfascial blockade, the blocking of the cutaneous branches of the intercostal nerves in the axillary line (BRILMA) associated with a multimodal analgesic regimen improves post-operative analgesia and allows saving opioids after non-reconstructive surgery of breast.

MATERIAL AND METHODS

A prospective, randomised and simple blind study was conducted on patients that underwent non-reconstructive breast surgery. The patients were randomly assigned to the blocking group, or to the standard post-operative analgesia group (paracetamol and dexketoprofen). The main variables analysed were the pain intensity assessed by the verbal numerical scale and the analgesic rescue needs with tramadol.

RESULTS

Statistically significant differences were observed in the consumption of tramadol during the study period (10.5mg in the BRILMA group, compared to 34.3 in the control group, P=.0001). There were also differences in the pain assessment, with lower values found in the BRILMA group.

CONCLUSIONS

In non-reconstructive breast surgery, performing a BRILMA block allows obtaining lower pain scores, which implies less need for rescue analgesics and a significant saving of tramadol in the study period.

Analgesic efficacy of modified pectoral block plus serratus plane block in breast augmentation surgery: A randomised, controlled, triple-blind clinical trial

INTRODUCTION

Prosthetic breast surgery is a very common plastic surgery procedure, but its postoperative analgesic management is a challenge for the surgical team. The purpose of the present study is to validate the analgesic efficacy of pectoral block and serratus plane block in retropectoral mammoplasty.

PATIENTS AND METHODS

A randomised, controlled, triple-blind, clinical trial was designed, and included 30 patients undergoing retropectoral augmentation mammoplasty. All of them had a modified PECII block and a serratus plane block with a total volume of 40ml per breast. In 15 of them bupivacaine 0.25% (GPEC) was injected and in the other 15 patients saline was used (GC). Standardised management of anaesthesia and postoperative analgesia was performed. Intra-operative haemodynamic parameters required for postoperative analgesia, and a numeric verbal scale on arrival in the recovery unit were measured and at 3, 6, and 24h. The quality perceived by patients and surgeons was also measured.

RESULTS

Post-operative pain was significantly better in GPEC (5.3±2.3 vs. 2.9±2.7; P=.018). No significant differences were observed at 3, 6, and 24h. The surgeons rated the anaesthetic-analgesic quality as very good in 80% of the cases in GPEC versus 33% in CG (P=.01).

CONCLUSIONS

The use of these blocks is a good perioperative analgesic strategy in the multimodal management of retropectoral augmentation mammoplasty.

Botulism in the ICU: Nursing care plan

INTRODUCTION AND CASE EVALUATION

Botulism is a rare disease in Europe, caused by the bacterium Clostridium botulinum, notifiable, non-transmissible person-to-person and potentially fatal (between 5 and 10%) if not treated quickly. The favourable opinion of the Clinical Research Ethics Committee was obtained. We present the nursing care plan of a 49-year-old man with a diagnosis of bacterial intoxication caused by Clostridium botulinum, secondary to ingestion of beans in poor condition, who was admitted to the ICU for a total of 35 days.

DIAGNOSIS AND PLANNING

Holistic nursing evaluation during the first 24hours, with prioritisation of the systems that were deteriorating fastest: neurological and respiratory. Nine diagnoses were prioritised according to the NANDA taxonomy: Risk for allergy response, Ineffective breathing pattern, impaired oral mucous membrane, Impaired physical mobility, Risk for disuse syndrome, Risk for dysfunctional gastrointestinal motility, Impaired urinary elimination, Risk for acute confusion and Risk for caregiver role strain.

DISCUSSION

The nursing care plan, standardised and organised with the NANDA taxonomy and prioritised with the outcome-present state-test (OPT) model, guaranteed the best care based on evidence, as the NOC scores improvement demonstrated. It was impossible to compare the nursing intervention with other case reports.

Randomised trial comparing the transversus abdominis plane block posterior approach or quadratus lumborum block type I with femoral block for postoperative analgesia in femoral neck fracture, both ultrasound-guided

INTRODUCTION

A double-blind randomised controlled trial was conducted to compare the analgesic effect of the transversus abdominis plane block posterior approach or the quadratus lumborum block I versus femoral block, both ultrasound-guided.

MATERIAL AND METHODS

Prospective study with parallel groups with 104 patients with neck of femur fracture undergoing hemiarthroplasty (although 7 participants did not finish the study). The inclusion criteria were patients older than 65 years old, ASA I-III status, who required and gave their consent for hemiarthroplasty. The exclusion criteria were patients with known allergy to local anaesthetics, mental disability, peripheral neuropathy, a coagulopathy disorder, and those patients who received morphine, or a block was performed previous to the surgery. Each patient received one block followed by a spinal anaesthetic technique, performed by the anaesthetist. Pain was measured using a visual analogue score, sensory blockade using cold spray, and motor blockade, evaluating the leg movement. These were compared on arrival in recovery and at 6, 12, 18, and 24h later. Total opioid amount administered in 24 hours, duration of stay in post-anaesthesia care unit, patient satisfaction, and adverse effects were also recorded.

RESULTS

A lower visual analogue score was observed in the quadratus lumborum block group at 6, 12, 18 and 24h (3.7, 1.4, 0.8, 0.7 versus 5.2, 4.6, 3.4, 2.6 in the femoral group, P<.01). Opioid use in 24h was lower in this group (9.7 versus 16.9mg in the femoral group, P<.01). The sensory and motor blockade, satisfaction, and adverse effects, were similar in both groups.

CONCLUSIONS

Quadratus lumborum block is an effective analgesic option to be used in patients with neck of femur fracture. More clinical trials are required to validate this.

Ultrasound guided nerve block for breast surgery

The breast surgery has undergone changes in recent years, encouraging new initiatives for the anaesthetic management of these patients in order to achieve maximum quality and rapid recovery. The fundamental tool that has allowed a significant improvement in the progress of regional anaesthesia for breast disease has been ultrasound, boosting the description and introduction into clinical practice of interfascial chest wall blocks, although the reference standard is still the paravertebral block. It is very likely that these blocks will change the protocols in the coming years. A review is presented of the anatomy of the breast region, description of nerve blocks and techniques, as well as their indications, all according to published articles and the opinion of the authors based on their experience.

Location of the sciatic nerve at the popliteal fossa in the adult population: Relationship with gender and anthropometric data studied. Implications for daily practice

OBJECTIVE

To determine whether the location of the sciatic nerve (SN) at the popliteal fossa is related to anthropometric variables in the adult population, and to identify possible anatomical variations and their possible implications for clinical practice.

MATERIALS AND METHOD

Prospective observational study in elective ambulatory surgery patients. Patients were examined using ultrasound, looking at depth, laterality and distance at which the SN bifurcates at the level of the popliteal fossa. These measurements were linked to gender and the anthropometric data of the patients.

RESULTS

A total of 62 patients were included, with 124 measurements. A statistically significant association was found between SN depth and the diameter of the thigh measured at 10 cm from the popliteal crease (P<.001). Mean depth: 3.32 ± 0.8 cm, mean laterality: 1.43 ± 0.9 cm, mean SN bifurcation distance: 61.78 ± 12 mm and mean SN diameter: 7.45 ± 1.17 mm. There were no statistical differences when comparing the measured variables with the age and gender. Similar results were obtained between measurements when comparing both lower limbs in the same patient. There was no statistical difference between height and distance at which the SN bifurcates.

CONCLUSIONS

The depth and laterality of SN are independent of gender, weight and height. The depth at which the SN is located at the level of the popliteal fossa is related to the diameter of the thigh. The bifurcation of SN in popliteal fossa is not related to height.

Postoperative analgesia with transversus abdominis plane catheter infusions of levobupivacaine after major gynecological and obstetrical surgery. A case series

Transversus abdominis plane block has become an important method of postoperative pain management for patients undergoing abdominal surgery but the modest duration is a major limitation. We report the successful use of a novel TAP catheter technique for continuous infusion of levobupivacaine in six gynecologic and obstetric patients. Bilateral TAP catheters were inserted at the end of surgery by ultrasound imaging using a Contiplex® C needle (B. Braun, Melsungen, Germany) in the Triangle of Petit or in a postero-subcostal level based on the location of the surgical incision. Following negative aspiration, 0.25% levobupivacaine 5 mL was injected. After withdrawing the needle, while holding the over-the-needle catheter in place, bilateral continuous infusion of 0.125% levobupivacaine at 2 mL/h from elastomeric pumps (INfusor SV2, Baxter, France) was started and continued for up to 50h. Before removal of the catheter, a bolus of 10 mL levobupivacaine 0.25% was administered. Successful analgesia was achieved in all six cases utilizing continuous infusion of levobupivacaine, minimizing the volume required. TAP infusions produce significant opioid sparing and better patient mobility. This technique may be a reliable alternative to neuraxial analgesia in major gynecological and obstetrical surgery.

[Treatment of a patient with refractory cardiac arrhythmias using stellate ganglion block. Access by the classical and ultrasound-guided approach]

Stellate ganglion block is a technique that is often used by anesthesiologists for the treatment of complex regional pain syndromes of the upper extremity. This technique interrupts cardiac sympathetic innervation and has been proposed as treatment for refractory arrhythmias. We present the case of a patient with arrhythmias that were refractory to pharmacological treatment, and were finally treated by continuous stellate ganglion block. Left stellate ganglion is a lynchpin of cardiac arrhythmias due to being a structure where the majority of postganglion sympathetic fibers responsible for preferentially innervating the atriventricular node, bundle of His and ventricular mass are originated, fundamentals in the origin and maintenance of ventricular arrhythmias.

[Joint and sensory branch block of the obturator and femoral nerves in a case of femoral head osteonecrosis and arthritis]

The sensory innervation of the hip joint is complex. The joint and sensory branch block of the obturator and femoral nerves is effective for treating the pain caused due to different hip diseases. This could be an option to be considered in certain circumstances such as, being a surgical-anaesthetic high risk, or if there is significant overweight, It could also be useful on other occasions if the traumatoligist considers that it is better to delay hip replacement for a limited period.

[Ultrasound-assisted approach to blocking the intercostal nerves in the mid-axillary line for non-reconstructive breast and axilla surgery]

INTRODUCTION

Several nerve blocks have recently been used for pain treatment in breast surgery. The main objective of our study was to determine the efficacy and safety of ultrasound-assisted blocking of the anterior and lateral cutaneous branches of the intercostal nerves in the mid-axillary line for non-reconstructive breast and axilla surgery.

MATERIAL AND METHODS

A prospective observational study was conducted on 30 patients scheduled for non-reconstructive breast and axilla surgery. An intercostal branches block was performed in the mid-axillary line with 0,5% levobupivacaine (3ml in each intercostal space). Clinical efficacy was assessed by standard intraoperative hemodynamic response to surgical stimulus and the need for opioids, and in the postoperative period, by assessing pain intensity as a verbal numerical scale and the need for rescue treatment. We also evaluated the quality of sleep the first night after surgery, any adverse events that occurred, and the satisfaction of patients and surgeons with the anesthetic technique.

RESULTS

The intercostal branches block in the mid-axillary line was effective in most cases, with only 2 patients requiring intraoperative opioids, and in one case analgesic rescue was necessary in the postoperative period. The duration of postoperative analgesia was 19±4h. There were no notable adverse events or complications. The satisfaction with the chosen technique was assessed as "very good" in all patients, and by 97% of the surgeons.

CONCLUSIONS

Intercostal branches block in the mid-axillary line provides adequate intraoperative and postoperative analgesia for non-reconstructive breast and axilla surgery. It is a simple, reproducible technique in most patients of this study, with an easy to understand ultrasound anatomy, in which adequate analgesia could be provided through a single puncture, and may be an alternative to neuroaxial blocks.
